Windows and Overspray

[Beefer]

I figured I'd post this here.

I repainted the trim around my cabin windows, and didn't realize it isn't glass, but rather acrylic or similar. I got overspray on the windows, and was going to take it off with a razor, but that is causing lights scratches. Using Goof-Off (or Goo Gone) does ok, but is difficult where there is primer and paint (where it's just paint it comes off pretty good). Is the Goof-Off my best option, or will it damage the window? Also, how do I now get rid of the scratches?

Re: Windows and Overspray

you can buff glass just like you buff gellcoat.....just use a dry mop on the buffer.......2000 rpm

i knocked some good scratches out of my sisters windsheild with my buffer in just a few minits

Please excuse me for butting in here but I do believe that the part about it not being glass that you are working with was missed by those who have replied. What they suggest will be just fine for glass but doing those things to plastic can get you into trouble. I am sure that they will agree. Lacquer thinner can get you into trouble quick. It will soften the plastic and also make it cloudy. Buffing it with a 2000 RPM buffer might be okay if you use very little pressure and a wet application; dry/heavy pressure will burn/ heat the plastic and you could end up with the fibers from the buffing pad being embedded into it permanently.
Use the Goo Gone if it is working and not causing damage. Take off as much as you can like you are. Then for the places that do not come of easy use some 2500 grit wet paper to sand it off. Tape off painted areas that you want to protect with at least two layers of tape. Use plenty of soapy water, dip a sponge and drip it with one hand and sand with the other. (Use a rubber sanding block to hold the paper) Rub it a couple times and then check your progress. When all of the paint is off, you?ll need to hand rub the sanding scratches back out. Start with an aggressive compound followed by a medium and then a finishing compound. You can use a 2000 RPM buffer IF you are very careful and you do a wet application but that will make a mess of anything not covered. If you don?t mind the extra work, cover everything and then have at it. Drip the soapy water on the plastic as I described above. Keeping it wet will help prevent it heating up and fibers or foam becoming part of your windshield.

Re: Windows and Overspray

I think Campcook has it right about someone not realizing its not Glass .. ( bondo however is correcto on masking everything before you spray ).

Plexi is actually fairly durable. I have used a DA with 400/600/1200 then buff to get scratches out of hatches.

Can you post up some pics ?

If not..then just use a combination of your goo gone and a razor for most of it..then wetsand and buff it out. ( Do not go back and forth on the Brand new razor .. only one direction )

But CC has it basically spot on.

YD.

Re: Windows and Overspray

Yeah, I had a feeling the above advice wasn't the right solution. Thanks campcook for catching it, and for the info. I did go back again with just the goo-gone, and it took awhile, but I got it off. As for the scratches, I have a kit for polishing scratches out of aquariums, and I'll give that a try. If I had realized it wasn't glass, I definitely would have masked it off from the beginning. I did the windshield (which of course is glass), ad=nd didn't give it a second thought when I moved to the cabin windows. Luckily, I only did one side that day, so I can redeem mself by masking the other side properly.
