Do not ever use thinner,acetone or reducer to wipe before paint,unless it's bare metal or some tractor.

Use prep-solvent that is designed for precisely wiping parts down prior topcoat.

Do not use rattlecan or cheap lacquer based primer.Only 2-part primer should be used on anything that you want to last.

If you don't want to use prep-solvent,buy 3M grey or red scothbrite pads for final prep ,you can wash with water and dry with clean lint-free cloth. I prefer using microfiber towels before paint,because there is zero lint. I've tried many towels and nothing beats microfiber.
