it seems a hard paint to use and risky on spray gear... no problem about its hardness.
gotta say I am happy with good quality 2k .
used 1lt of kbs on the toilet wall to protect from graffiti , it goes off pretty quick .
All ways test on a old playfield first , get a good game plan , then if all good attack the real job knowing its gunna be ok, 99% chance of being good.
best of luck
