Ive never really had a problem with the paint I use scratching off, the white that's in there now is a plastic spray on dye, I've rubbed/dropped screwdrivers on it and haven't had a problem, it could just be the way I prep the surface, I use 3 different chemicals to make sure there are no contaminants whatsoever. When I use regular paint I use an adhesive promoter, then primer, then paint with a heat gun in between.
.
That is a good ides though, test the durability of the coatings I use, I guess ill be going to the junkyard in a few hours to grab some random parts from different manufacturers cars.
