As Pickleboy stated, I've heard of a number of different methods for solvent tests. For poly's I used a 10% MEK/90% Xylene mix for 50 double rubs. No effect on the coating. After that I tried MEK alone. Usually only use that on epoxies but it didn't cut through the TGIC. It did soften the surface but if it wasn't cured I would have expected it to go down to the part or at least make a mess.
Think I will try Pickleboy's suggestion of waxing before any handling. I have waxed after the fact and it does help hide.
Anyone tried a different type of gloss black powder that resisted scratching but was still had good weathering properties?
