Just be aware that any scratch Resistance and UV protective coatings will be removed. Maybe try just the plastic headlight polish by itself first. That may be enough for a decent improvement. I would also caution against using any compound that is not specifically for plastic. Automotive compounds and waxes have petroleum solvents that will attack plastic in a way that cannot be fixed.

Hello all,

Our 37/40+ has tinted plexiglass sliding companionway hatches that look fogged and lightly scratched all over from years of sun. After reading here and other places about potential ways of curing the issue, I ran a test here at home. I have a Ryobi Corner Cat, and grabbed a piece of scrap plexiglass. Starting with 360 wet/dry sandpaper, I wet sanded the nice new piece of plexi until it looked like $#!+. Then followed with 600, 1200 and 2000, then went to buffing compound, and finally to McGuire's polish for headlights.

Sure enough, the piece of plexiglass came out really nice & clear.

So, I think I'll try it on the sliding hatchboards unless someone here cautions me otherwise.

What say you wise folks?
