Just got a pretty nice Firepower back glass for a resto I’m in the middle of. This glass has a few scratches.

I paint all the black areas by hand and from the front you can’t even tell there were scratches in those parts.

So I move on to the yellow and I did the cracks by hand. Again from the front looks awesome. But once you put light behind it, it looks extremely obvious and awful.

So I wiped off the touch up and set up the airbrush and tried painting the entire area. Again looks amazing from the front unlit. But put some light behind and it looks like crap.

So are you pretty much screwed when the glass is scratched or is there a technique for painting the areas that are intended for light to shine through and not make it look like crap?

First attempt by hand. Looks fine without lighting. But awful back lit. (Didn’t take backlit pic)

So basically the opaque parts are fixable but the translucent areas really cannot be repaired to look seamless?
