Prism polish is specifically stated by the manufacturer to be safe for
plexiglass.
"Prism Polish has been formulated to clean, polish and protect all
metals in one application. Our protective coating is designed to last 3
to 6 months. Prism Polish contains no harsh acids, caustics or
abrasives; it’s safe on all metals, fiberglass, Gel-Coat, Plexiglass and
painted surfaces. Prism Polish has been developed for use in the marine,
aviation, automotive, motorcycle and maintenance industries. Use Prism
Polish on bronze, brass, copper, stainless steel, chrome, aluminum,
pewter, nickel, sterling silver, silver plate and factory blued guns.
Test plated metals in an inconspicuous area before use. Prism Polish is
excellent to clean and deoxidize fiberglass; it removes cloudiness from
plexiglass, clean vinyl, eisenglass or lexan."

FYI:
I got some Prism polish for my stainless steel grill. One of my old
cars has foggy headlights that nothing seemed to fix, so I figured
nothing to lose and the Prism stuff did GREAT on the headlights.
(also did great on the grill)

test, now to try it on our companionway hatches...
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?
