Wash with dish soap, like, fairy liquid type stuff? So this takes off whatever wax is still on?
Dish soap is very harsh. Unless you are going at your paint for a "hasn't seen care in years" hard core polishing event, use a car-specific wash.

Any polishing/ buffing/scratch removal happens now right? Can someone (initialdave?) recommend a coarse -> fine serious of cheap compounds, also I'm willing to buy a buffer if this saves me weeks of lovely labour, what's a good starting point?

The Porter Cable Buffer is the standard. And it's worth it. I've had mine for over 12 years and it is as solid now as it was then.

Meguiar's has a "Body Shop Professional" line of buffing/polishing compounds that go from course-as-fine-sandpaper to final polish.

Does clay bar happen now or before the polishing?
Before.

quote:

Wax to protect all my hard work now? Recommendations as well please.
This is largely subjective. I've tried over 30 different waxes and I keep coming back to Meguiars #16 Paste Wax. It's not sold in the US anymore because of some nasty chemical component, but you can still order it from Canada. It's labor intensive, but leaves a fantastically deep, hard shine. I don't know if it's available in the UK.

Another thing I found recently is Turtle Wax Ice Wax. It's not a very good wax, but you can use it on/near black plastic parts without leaving residual wax marks. I use it on my Volvo XC90 that has black plastic everywhere and it saves TONS of time.

I have access to all of Zymol's line. I use everything but their wax, for what it's worth.

This is kind of half-bodywork, half detailing, but we recently got a '99 Grand Cherokee Laredo, and it has that grey body cladding on the bottom edge. It's faded, splotchy and just generally gross.

What would the general process be to restore this to either a nice dark gray, or to black it out? I basically don't know if Back To Black will do the job or not. Vinyl dye, maybe?

We are thinking of taking the front grill black as well, as the fake-chrome on the plastic is starting to peel. Any suggestions on how to strip that crap off?

The best way to restore faded plastic like that is a bit sketchy... it involves a propane torch and "bringing" the black back. For gray, I don't know of a good way, sometimes the gray shows the way the plastic ran in the mold and that "marbling" is usually permanent.

Why would you? If there's light dust or pollen on it, you can use an old school "California Magic Duster" or whatever. If it's more that superficial (something you couldn't blow off with your mouth), then it needs to be washed.

For bird poo poo and the like, getting it off the car as soon as possible is your best bet. If you just spray it down and don't finish the wash, you run the risk of water spotting, but that would probably be preferable to having the bird poo poo sit on the car in the sun, anyway.

Still needs properly washed as soon as you can, though.

So, in the above picture I've started polishing the square in the upper left of the photo. I'm using the PC7424XP and started with an LC Orange pad with Meguire's 105 and then finished it with an LC white pad and Meguire's 205.

I think you need to get a more aggressive compound. Something like Meguiar's #83 Dual Action Cleaner/Polish or even careful use of #85 Diamond Cut Compound.

When you actually start taking material away, you obviously need to be extremely careful, but it can give tremendous results. On the single-stage black I had on my old Miata, there were a couple times that I went full-on with it, using #85 Diamond Cut over the whole car. Diamond cut will leave your finish looking like you went at it with sandpaper. But, polishing it back through the various steps (I went from the cutting compound to #83 to #82 and then to wax) resulted in an unbelievable depth and gloss.

What is the plastic bag test? Do I need a buffer to clay the car? Is using the clay bar pretty self explanatory? I suck at this.

Clay bar is super easy, three components -- the clay bar itself, a microfiber wiping towel and lubricant. You can spend a lot of money on "specific clay bar liquid," or just put a few drops of Johnson's baby shampoo into a spray bottle filled with water.

Spray a 1'x1' area with the liquid, rub the clay using light-to-moderate pressure. You'll clearly be able to feel the area that you've clayed in comparison to the unworked area. The clayed area will be substantially smoother.

Your link was regarding using a Magic Eraser for bird poo poo removal... if you do that, you're dumb. But to quick fix scratches already in the paint? Magic.

? He said use compound and you will see the same scratches. I am saying if you use compound correctly you won't.

I'm saying that if you use a Magic Eraser properly, not going at the finish like a monkey on crack, that it will be fine. And the Magic Eraser WILL take care of minor scratches like magic with no ill effect.

Alternatively, you can also use rubbing compound and put the same kinds of scratches in paint as GTi_guy's link showed, if used on a perfect finish underneath strong florescent lighting.

As a matter of fact, MOST cars that are not complete garage queens will have paint that looks lovely and scratched up underneath strong florescent light, yet still look beautifully finished in natural light. That's why I use florescents in my garage -- if you can make something look smooth/glossy/clear under florescent, then you're done.

To put a perfectly polished panel under florescent light, then rub on it with a Magic Eraser and use it as an example to claim that you should NEVER use a Magic Eraser on paint is disingenuous. There is nothing "magic" about it, it is simply another type of abrasive and, as with any abrasive, you can gently caress things up if you use them incorrectly.

The fact is that I have an extremely critical eye for paint. I was employed by a detailing company in the '80s. I have done contract work for Zymol. I know a thing or two about paint care. I use a Magic Eraser for many things with a car, including the finish, and have had nothing but good results*.

(*noted exception: pearlescent paint. If you have a scratch in a pearl paint, the magic eraser will soften/tear the pearl coat. I've seen that on multiple cars. You have to use your head, just like anything else.)

I bought a car a few weeks ago with a set of enkei lusso (black w/machined lip) rims. The black holds up pretty good, but the machined lip is starting to get a bit dull. What might be the best way of polishing this up? I bought a $10 polishing set for my dremel at walmart, but I figured I'd check here first before going hog wild on it and potentially loving it all up.

I know there are different tools/methods to use for wheels with/without clearcoat but I really can't find much info about these wheels.

Be careful, those wheels probably have a clearcoat. If you use a dremel with metal polishing stuffs, you'll trash the finish.

General rule of thumb is to use the least abrasive product possible to get the result you're looking for. Try a basic cleaner/wax first and see if that makes a difference. If it does, then you're set. If not, take a closer look to see "how" the finish is getting dull, is it scratches, build-up or a hazing of the clearcoat? Each of those have a different method to rectify the issue.

Can someone explain to me why a proper porter cable or the likes is better than simply attaching a pad to a hand drill for polishing? I know it is better, but I need to know why so I can justify my Christmas present to the wife :)

Porter Cable and the like are random orbit buffers, whereas a drill with a pad is simply circular.

A circular pad is not a bad thing in the hands of a professional, but with someone inexperienced, it is easy to scratch semi-circles in the paint at best and cut through the paint entirely at worst.

Basically, the random orbit buffer makes it easy to polish and difficult to damage paint.

That's not true at all. A scratch stick followed by touch up would be fine. That surface rust comes right off with a scratch stick, leaving nice and fresh metal to coat... unless the scale is off and the rust is more than the 1" or so in length that it looks like here:

The scratches in the side -- take a magic eraser to them, it'll knock down some of the contrast, then give it a thick wax. It'll never look right, but it'll blend more than it is right now.

I'm reading up on it and apparently one of the tricks is to use conditioner first to humidify the leather and lift the dirt up, _then_ use the cleaner.


The magic eraser is a VERY mild abrasive. If your seats were new, they wouldn't do much to the leather surface. However, your seats have a layer of straight dirt on them that wetting/magic erasering will remove. After you're down to a suitable surface, then get to the leather treatment. And don't get too wrapped up with leather cleaning theories, a straight leather cleaner, followed by a leather conditioner will have them looking much better than what you see now.

My first reaction to just about anything like that -- Magic Eraser. That will let you see exactly what you're looking at. There's a good chance that those white stripes will come right off and you can smooth the scrapes out enough to polish and call it good. You'll always be able to see it, but you can knock the "noticeable" level down a ton with a simile ME/polish.

While I'm quite the proponent of the Magical Erasers, that's the wrong application for them. With tree sap, letting some warm soapy water sit on the surface for a while often is enough to soften/remove the sap. If that doesn't work, clay bar is the trick -- make sure there's plenty of lubricating liquid.

Depends on your definition of "match" and the color of the car. If it's a color with a strong metallic, that can be problematic... but still it would look better than rust.

What color is it? Most often, going to a store with a large automotive department will allow you to pick from the large Duplicolor display and pick what you think is closest. In general, if nothing is an exact match, get as close as you can, but a little darker.

If you are polishing the door jambs/side areas of the doors, always have the pad just touching the area of the car you're polishing (just a sliver of the pad on the vehicle, the rest of the pad in air). Never angle the buffer to that you are hitting the edge of the door while you're polishing a flatter part, that is going to localize the abrasive force and strip the edge of the door skin.

The scratches were on the rear doors, in hindsight should have just kept the stupid driver side door closed. I didnt angle the buffer at all, i tried to stay away from the edge but enough of the pad was making contact that it hosed it over. Before the wrx i did my entire 99 mustang gt and did some pretty major scratch correction on that too.

Just a warning to others, i saw the video of the porter cable being smashed on the hood of a corvette years ago, i understand exactly how hard it is to burn through paint on a flat surface, but take strong precautions when approaching edges of paint where it could be a lot thinner. I dont trust meg 105 for poo poo when approaching edges anymore, ill only use it on expansive flat surfaces.

You should be EXTREMELY careful with 105. 105 is a cutting compound, like the old-school-named "Rubbing Compounds." It doesn't matter whether you have a microfiber cloth, porter cable or newspaper, you can tear the poo poo out of paint with 105/similar compounds (even flat surfaces).
