I have to go with yes, I didn’t dare to try and scratch my actual board, but I did try to grind my nails into my test one, and nothing happened, while I can for sure tell you it damaged before without…. I can’t speak for any success with other variables… but from what I printed on and the spray I used was a win.
When I got my maps, I was told it don’t scratch… so to varify we tried to scratch one of their demos… he was surprised how easily it scratched, thus why I got a free print to test to make it more resistant… but ya, you gotta clear coat it.
