For spot treating on a horizontal surface, fill a cup with warm water and a drop of dish soap, cover the opening of the cup with an index card or whatever you can find, flip the cup over, then place it onto the sap covered spot (card side first), pull the card out from under the cup and let it soak. If it's a vertical surface or just one of those tricky curved surfaces, you can kind of use clay around the rim to form a gasket to keep your fluids from spilling before a good soak sets.

You'll have to find a way to scale this to a larger size if you're doing more than a small spot treatment - a warm/hot soak and a grit sponge may do the trick, followed by the claying to get the rest out, then the usual glaze/seal/wax to make it easier to remove in the future.

Don't use melamine foam products on your paint, it's too abrasive and will marr the poo poo out of it.
