Impact sockets are actually softer than regular chrome sockets, so they don't shatter.

Don't forget, impact sockets are also thicker than regular sockets, so clearance is often an issue. The Harbor Freight and other ultra-cheapo impacts are often significantly thicker than name brand ones, to try to compensate for poor manufacturing. Sometimes that works, sometimes it doesn't.

Why go with air tools over electric ones? From what I can tell the air ones have more torque, and it seems like if you need a variety of powered tools air ones are much cheaper because all the energy comes from your compressor, so each tool is cheaper. The electric ones seem a little wimpier and have a smaller initial investment (also don't have to worry about running out of air), but if you need multiple tools could be more expensive in the long run. Is this pretty much it?

It seems like if the only powered tool I really need is an impact wrench I'd be better off buying a $35 HF electric impact wrench rather than buying a compressor and air impact wrench, unless I needed the additional torque that the air tools have. Anything I'm missing?

Aside from the torque issue, pneumatic tools have a longer service life, and are smaller/lighter for their power. Electric motors generate a ton of heat, especially under load. Pneumatic tools stay cold (literally). Imagine an electric die grinder or cutoff, running 22k RPM at 1/4HP or whatever.

can anyone recommend me what sort of compressor I should be looking at for painting a car? I'm going to start with laying some killrust down, so any info on different spray guns and stuff would be useful also. Later on Ill be painting the car body from primer to base coat to top coat to clear coat.

I know I probably want at least 2hp, electric and a good size tank - would 40L be sufficient?

To make the most of the purchase i'll probably get some airtools also, so it will need to be able to run most generic tools as well.

What other gear will I need? moisture traps and stuff? What kind of spray guns are best? Gravity feed?

Assume I have nothing and know nothing . A list of stuff I should shop for to paint my car would be awesome


Heh, this is a pretty big question. Painting a vehicle is a massive pain, especially if you have any desire to make it look good.

In general, you want a minimum 5hp (real hp, not peak) compressor that puts out at least 15cfm @135psi. The bigger the tank, the better. I don't know what comes standard on that size compressor, but I'm guessing 40 gallon. That would be OK, but 60 or 80 gallon would be ideal. With my 80 gallon tank, pumped up to 175psi, I think it only cycled once for every three guns (~1.5-2L) of material I shot.

As for guns, DeVilbiss currently has a three-gun starter setup for like $150 that is a pretty good investment. It comes with a small regulator too, which is nice.

As for a filter, something like this DeVilbiss unit will do a good job overall.

At that point, you're looking at a little over $1k in hardware (plus whatever it costs to run 220V service for your compressor, if your garage isn't wired for it already). Figure at least $500 in materials after that for paint/primer/sandpaper. That is a low estimate, because a quality clear may run $350/gallon or more, and expensive colors aren't far behind that.

You'll also need a bunch of sandpaper, with grits varying based on how much body work you are planning to do. 400 wetsand will be OK for prep before your color coat, depending on what is underneath.

Are you going to take the vehicle to bare metal? Are you going to do a one or two stage paint (single stage is color only, two stage is a color basecoat and a clear topcoat)? Buy a decent, high quality basecoat. Just like house paints, the cheap color coats don't cover as well, and require more coats. They end up not looking as good, and you spend just as much because you have to use so many coats. Then you're out considerable time as well. For clearcoats, it isn't as much of an issue. I have had very good luck with PPG's cheaper Omni clearcoat.

The quality of a paintjob is 99% dependent on the prep work. Can someone get good results with with a 2hp 40L compressor and a Harbor Freight gun? Sure, people probably do it all the time. Would I bother? Not a chance, but that's me. Aeka may have some input for you on painting with a smaller compressor.

The actual spraying, while very messy, isn't terribly difficult. Really, it all depends on how good you want it to look. If you're starting with a clean vehicle with good paint already, and you don't need to do any body work, it isn't a huge deal. Add in bad old paint, or any body work, and things get very tedious, very quickly.

I kept the garage door only open enough so that I could close it on top of a box fan at one side, I also cracked open the side door of the garage. The wind had to be perfectly still to do this.

On that note, I ran four box fans, with the garage door sitting on them. The rest of the garage opening was covered with cardboard. Make sure you have a way for air to get IN with a system like that. I put those big, blue, cheap HVAC filters over the back of the fans to keep the blades from loading up with overspray. I also wet the floor with a hose to keep dust down.

One other filter note. I also used a disposable water/oil filter at the gun. I don't know how much it did, but I never had a single fisheye or water issue. Which reminds me, clarifying somethings Aeka said about silicone lubricants. If you've sprayed WD40 or used Armorall in your garage in the last month or so, don't bother trying to paint.

Here's another tip: Avoid painting after 4:00pm, and never paint at dusk. That is when the bugs *really* start to come out. Paint in the early morning, if you can.

For the air ratchet crowd, try using a 1/4" air ratchet. I almost never use my 3/8" unit, but have *many* hours on the 1/4". Also, the 3/8" ratchets are broken bones waiting to happen. I have had a few situations where it has pinned my hand somewhere, or caught me by surprise and done some damage. The 1/4" is smaller, and lighter, which makes it easier to move around, and is perfect for all those torx, hex, and <15mm bolts and nuts. I rarely pick up my non-pneumatic ratchets anymore (except for 1/2" jobs). This is especially true for almost every job I have to do on my motorcycles.

Agreeing with this. A compressor that can keep up with the demands of sandblasting an entire vehicle will run you tens of thousands of dollars; then you need to purchase the actual sandblasting stuff. If you try to use one of those little spot blasters you will want to kill yourself after the first hour it takes you to blast a quarter of a fender that you just warped to poo poo from the heat.

I'll have to disagree here. You can get a 15hp IR unit, pumping ~50ACFM @175PSI for ~$3.5k. Pretty much anything over 7.5hp is going to be three phase, ruling out many residential users, but that isn't the argument. The price is WAY less than tens of thousands of dollars, and I guarantee that no professional, let alone portable professional, setup requires more air than that.

I've done a few hundred hours of blasting using my 7.5hp unit (single phase), which is pushing 26ACFM @175psi, and it can catch up like I'm not even using air, when I'm sandblasting.

I'm not saying the guy should do it himself, but it's certainly not out of the question to buy a decent compressor that can put out WAY more air than you will ever use.

Just something to think about for those planning to buy a tool kit package:

Check the list for the kit, and don't waste your money if they pad it with 12pt sockets. 12pt seems to be the standard for cheap socket sets, though they are inferior to 6pt sockets. There are *very* few 12pt bolts, and if you come across one, just buy that one socket. 12pt box wrenches may have more angle options, but that isn't true for a socket (since you can ratchet to any angle you want).

PS: Don't bother with 12pt box wrenches either.


I'm guessing 12pt sockets and wrenches are more common because the tolerances don't have to be as tight, so manufacturing costs go down. Manufacturer may be down, but frustration and rounded bolt costs go WAY UP.

Anybody have recommendations for a 6" DA sander? I'm going to be stripping down my Beetle this winter/next summer and I'm going to take it down to bare metal.

Air or electric, either is fine. I've got 200 gallons of air sitting in the garage so it's not like one is better than the other. I'd be perfectly happy spending up to $170ish, because this won't be the last time it's used. Nearer to $100 would be nice, though.


e: evidently air sanders are lighter and have more control.

If you're going down to metal, an 8" geared orbital sander works WAY better than a DA, though you may wish to use a random orbit sander to finish the job. The 8" sandpaper is quite a bit more costly, but it's worth it.

Something like this:

Should I go up to 8" when I'm sanding a car that's nothing but big huge curves? There are almost zero flat spots on the whole car. I'm pretty resigned to having to either blast the fenders or just sand them by hand.

e: 73 Super Beetle

Stripping paint with a 6" DA is an incredible pain in the rear end (depending on how thick it is). I would personally go the geared orbital sander route, because it just works so much better for removing material, and it is less likely to remove metal than a grinder with a sanding pad.

Those 3M abrasive fiber wheels are slick, but crazy expensive for a big job, and they don't work too well on thick paint jobs, in my experience. Plus, it seems like it would take forever to do a whole car with one.

Keep in mind that you have to switch the whole kit over to use the spoolgun. Everything below the Millermatic 212 (?) only has one in/out, so you need to switch gas, pull the MIG wire, connect the spool gun, etc (or so I was told). That is major incentive to go with a dedicated TIG setup, or get a 212 for $$$.

As an update, I just got back from Harbor Freight.

I'm psyched to have decent clearance next time I'm rolling around under my vehicles

As a related note, jack stands easily act as point loads, and it is a bad idea to place them on an unconstrained concrete surface (like a block not contained in a form), holes or no holes. Stacking items to support a vehicle is bad practice, in general, anyway.

Really, swapping to the spool gun and a different gas is a hassle that isn't worth it for anything most of us do. I wanted a Miller 251 or whatever, but realized that the extra functionality and potential to maybe weld aluminum some time wasn't worth 4x the price.

In short, a spool gun is nice in theory, but a dedicated TIG at a later date would be money better spent. Spend the cash on a solid welder first.

Is there any difference between that serial-usb converter and something like this:

or this:

I don't feel like dumping another $70 for the one at B&B (which happens to also be the place that responded to my tech support email), if there are cheaper options. Is the B&B converter functionally different than the others?

I feel like I looked into this a while back, and there was some potential problem with using USB (like the converters couldn't do everything the serial port could). I don't remember.
