Will lacquer thinner damage clear coat?
Lacquer thinner (any containing strong solvents like ketones , xylene, toluene, etc) will damage any paint, including clearcoat. A single pack acrylic clearcoat is most vunerable(thinners will destroy it.) , and 2-pack urathane is more resistant, but will soften on the surface and lose its gloss if wiped with lacquer thinners. Thinners for alkyd enamels is fine. It is a mild hydrocarbon solvent found in wax and grease remover, and won’t damage the paint.
