Anyone cleared a window? I have deep scratches in my shoe box back window. I'm thinking of clearing the whole window then sanding and buffing it.
no i have not i don't think it will hold up i don't think it will be as clear as glass can't hurt to try
i bet it wouldnt stick, no mechanical or chemical adhesion, probably not opticaly clear enough either
If it would work, the body guys would have been doing it for years. They have tricks, secret tricks...
How does that glass chip repair kit work, never tried one. Maybe you could slather that stuff on and buff it.
Have you seen a panel get spot cleared? If you look close the edge is always their no matter how much feather buffing you do. You would just be filling the scratches with clearcoat. I would try wax before the expensive stuff.
Ya I tried the scratch repair kit (commercial) it made it worse. I cleared a small square looks great from the outside. By the way I am a paint and body guy
Wait wait wait... Your going to heavy clearcoat the whole thing? Wow. Go for it. Use some adhesion promoter. Maybe tint it with drops of candy color before spraying.
Back in the gasser war days, there were many cars racing with dark tinted windows. Most of it was spray on window tint. It was on the inside, but held up for years. Clear on the outside... I would think it would get a fogged look after a while.
If you try it, you could sand the entire window for adhesion. The clear will fill the sand scratches. I would mask of a small square, 4 Inches or so and spray that to see how transparent the clear is. Posted using the Full Custom H.A.M.B. App!
I have tried the glass polishing kit . Spent a day or so sanding and polishing as per instructions , sure it helped but wasn't really worth all the effort . The glass came out a little wavy but still scratched, maybe they were too deep?
I'm sure you know that when clearing over paint sand scratches 600 or finer will cover. Do a test panel. Luck.
Not much to lose except time and the cost of the clear. I doubt it will hold up well, but what do I know. You gotta etch the glass somehow, DA with 800 or 1000? I like the idea of tinting it, in case the clear ends up not actually clear, not sure if the tint will settle down in the deep scratches.
Let's get fair dinkum here. Everybody knows the only way to get paint to stick to glass is to spray an area near the glass. As a result, the oversprayed paint will stick like shit to a blanket, but if you intentionally prepare the glass for paint, it will peel off.
Back in the 90"s I was working at a bodyshop where one of the techs put a bad scratch in a customer's hatch glass. They said they were going to make him pay for it. He spent 2-3 evenings of his own time first wet sanding with a dual action sander and then polishing. He just used ordinary paint polish products. When he was done, there was a slight wave in the glass but the scratch was gone.
I had a windshield polished once.[ Wiper scratches] Had some bad hallowing going on during night time driving.
We used to use jewelers rouge and water with a buffing wheel but it would leave a wave which gives a distortion when you look through it. This is a problem if it is in the windshield and you are stuck looking through it as you drive but you say it is the backglass so you may be able to live with it. However it is a messy time consuming job, you may want to bide your time and look for a better window cause they are fairly abundant compared to some.
I am curious as to what is scratching your glass? Seems unusual to have a reoccurring problem like this.
Try House of Kolor adhesion promoter. I have old cans,so don't know if they changed the #.ADHERETO AP-01 is the part # on the can I have. I have painted on the out side of the glass with this and it holds up good. It will scrap off if you try but if you take care of it it will be fine.Its made to spray over glass and chrome. Good luck. I am a body guy, this is old school tech...
