Quoted from loomis:how are these other people all doing these acrylic backglass touch-ups and having any sort of success at all, without addressing these issues?
I'm not sure but my guess is they don't. I can't speak for anyone else I commented on what worked for me with good results. Like I said it was alot of trial and error and experimenting with how much retarder or air brush medium I put in...I used to use 1 drop of paint and 2 drops of retarder as my base line...when I had it mixed to the proper translucency to match the area on the glass I was working on. The consistency of the paint was about the consistency of milk. I didn't paint as I did kinda of put a dab of my mixture then (because of the retarder) it would flow into the areas I was trying to repair this also helped with brush strokes...
Quoted from loomis:If you get a repair right, and then are satisfied, and then triple thick over the repair, does the second spraying of the triple thick on top of the repair diffuse the light again, and screw up what you had gotten right with the acrylics?
Triple thick doesn't act as a diffuser. All TT does is seal in the original art and your touch ups once you are finished.
All I can say is that you can touch up a backglass and make it look great! BUT it will never look "perfect" if you want perfect then you should probably either find one in better shape or pick up a reproduction because it will never be exactly as it was when it first came off the line.
