Windshield Cleaning / Paint Removal

Post by TonyKZ1 » Tue Jun 06, 2017 7:27 am

When I bought my Seca II, the p.o. had painted the windshield with a flat black color. I didn't care for it but couldn't find an affordable replacement windshield. So I've been trying to remove the paint with little success. Finally I found a paint removal product from Goo-Gone in a spray bottle at Menards Hardware Store. It worked, but took some time and some scrubbing with a nylon brush. Now I see why the p.o. painted it. I've still have some polishing to do to remove the haze / discoloration.

I was in a similar position with one of my bikes. I polished it the best I could but it still was yellowed and hazy. To repaint it, I would recommend painting the "backside". This way the smooth plastic acts like a clear coat for the paint on the reverse side and looks like a nice gloss black that won't be effected by bugs, stones , etc. that will hit it over time. Easy to clean too this way.

I would sand it out to 2k grit and buff it with some rubbing compound.

As radare says, you should scuff it all over, equally, with sandpaper, until it's all equally scuffed. Then wash the screen, change to a finer grade of sandpaper, and repeat. Continue repeating this procedure with ever-finer sandpaper grades. It will probably be transparent but hazy when you're done. Then buff the hell out of it with Brasso (it's ultra-fine, and much cheaper than jeweller's rouge) before applying a spray of Pledge. Pledge contains silica. If you can be bothered with all that, you will get it looking like new.

You might even go finer. In our Auto Body class, we have a fancy expensive 3M headlight polishing kit that works great for restoring yellowed headlights. With it, we go up to 3k grit, and then we use Wizard's Mystic Cut polishing compound to finish the job (not cheap, but excellent stuff).

Yeah, it's not bought for that job specifically. That's what they use for polishing fresh paint jobs in the shop. We just use it for that too since we have it and it's great stuff.

I wish we could as that would be great, but here in the U.S.I haven't found any ones on eBay or craigslist that weren't already cracked/broken/badly yellowed. Not sure what the shipping would be for one from overseas.

Go to your local WalMart and buy some 3M rubbing compound. I use it on everything from polishing the paint on my cars to removing yellowing from headlights. It runs about $5 as I recall. Get a $5 pack of microfibre cloths while you're there.

I promise it'll work out well for you.

Sand your screen with 400 grit wet or dry until all the haze/paint/residue is removed. Then step up to 600-grit (if you can find it, if not, go to 800 grit). Sand until all of the 400-grit scratches are out. Then move up to 1000, then 1500 and then 2000. Once you're done with 2000, put some of the rubbing compound on a microfibre cloth and begin buffing by hand. It's a ton of work but it works.
