Polishing Windshield

[CaptnC]

Is it possible to polish the windsheild on boats? Mine has abrasions from the curtains rubbing on it. Is there any way to make it clear again?

I've had pretty good luck removing light scratching from acrylic with automotive clear coat scratch remover and a little elbow grease.

Permatex sells a headlight lens restoration kit that works great on acrylic headlamp lens. I think it may work on that scratched windshield...

if you are talking about a plexiglass wind screen on a boat........i used a high speed buffer (wool bonnet) and some mild polish such as Maguires Scratch Out or similar product ( i may have used some 3M Finesse it II) and it buffed out like new.

Sanding may or may not be required. Depends if you have deep scratches. IF so, 220 then 400, then 600 grit, then compound. Next polish with Novus Nov3 then Nov2. Use the proper plastic buffing wheel with the polish. Here's a link for the buffing wheels and Novus polishes.

The automotive polishes work "ok" too. (orbital buffer and compound)

Don't use automotive polishes on plastic. The solvents in some of the compounds will attack the plastic and give it that fine hair line crack look.

You can sand the plastic but you should use a ultra fine paper. 220 is WAY to coarse. 600 is the lowest grit I would use. I like 800-1000 grit.

This is some good stuff. I have used it on plenty of boat windshields and head lights/tail lights on autos. Remember to use some type of wax thats made for plastic after you polish it. The wax will help protect it. (I spent 28 years in the bodyshops)....................

Take it to a plastic shop. They will make it look like new for about the same as what you will spend on material and they wont screw it up. Thats what I did.

Ditto on the Meguiar's PlastX shown in his post. Excellent for the plexiglass winshield. Then protect with Rejex, or Meguiar's NXT.

Used that Meguiars PlastX on the windshield of my Sailfish 266. Eisenglass had touched and abraided it in two places.

GONE. There may be some bumps you can feel but not see. GONE.

Buy it.

Thanks a ton guys!

I am a D-I-Y-S'er plus where I am there is no one to "take it to"...if I did they would be like "you want to do WHAT?"

OK....so where do you get this stuff?
