Author Topic:   rubbing compound on windshields

newt posted 07-25-2002 02:08 PM ET (US)
The windshield on my '84 montauk shows swirl marks - probably from improper cleaning. The whaler website says to use rubbing or polishing compound to remove fine scratches.
Has anyone tried this method? Or any other advise?

Try using the finer automotive clearcoat polishing compounds first. They work well buffing up plexiglass. Only go to harsher compounds if needed, and then you will have to buff your way back up through the grades. The clear hatch covers over the Outrage gas tank gauge can also be polished up this way.
I think 3M also makes plastic scratch removing compounds.

Go to a professional paint house or avaition supply house, Meguiars makes a special polish for aircraft canopies, I have used it on aircraft and automobile convertible top windows.

Newt,
Go to the following website:
www.meguiars.com/
Then click on products, then Tools & Accessories, then Boat Interior Care. Look at M1708 Mirror Glaze Clear Plastic Polish. There are also other products on this page that may do what you wish to do.
Hope this helps:
David

I don't know about rubbing compounds but I polished out the plexiglass on my Outrage with a product called Micro-mesh made by Micro-Surface Finishing products, Inc. http://www.micro-surface.com/ The kit I had was the "Scratch Removal and Restoration Kit, KR-70".
It is a collection of progressively finer and finer abrasives (cushioned sanding cloth) that you use in a very precise sequence. Using a soft pad and water you wet sand the plexiglass. The grits contained in the kit go from 2,000 to 12,000
It was originally designed for polishing out the windshields on jet fighters. Look for Micro-mesh at an aviation supply house.

Do the meguires or 3m micro-finess($29/qt) for great results. I bought this clearcoat safe polishing compound made by "kit"(cheap crap)on sale for like $2 but it works great on that stuff.

I tried the meguir's (Plastic Polish) this weekend. It made a huge differennce with litte effort. The "haze" is gone, but I am still left with the existing swirling scratch marks.
I guess some heavier duty compound is in order. Or perhaps some wet sanding first.

Some of the sand sparkle and cracks are too deep and will remain. It is from flexing if in the corners.
