It is all about the surface adhesion. You could put 100 coats on something with bad adhesion and it would come off. I am thinking it might be the case material texture as it was fine on the rads that were smooth
Its about surface are. A textured surface has a much greater surface area. giving the coating more adhesion per sq cm . The existing case is powdercoated not painted etching to powdercoat can be tough.
That's what I was try by to say. Thanks for clarifying it like I couldn't.
texture holds paint better, that's why its usually better to sand whatever you're going to spraypaint, so that logic is kinda backwards haha. It probably had to do with the material the rads are made of and the kind of spray you used, adhesion varies between substances. But textured is better 9/10 times
To a rough texture it will stick better yes, but the inside of the case was like a hammered texture and it all could not be scuffed because of the little divets is what I am saying.
Gotcha. My case is a Define R6, it scuffed up where the top radiator plate lays down on the frame, the PSU shroud edge, some of the areas around fans and I/O slots, even the outside of the frame, etc. A shame really.
Yeah there is really no reason it should not have stuck to the scuffed up surface unless it somehow had contamination on it. Most things I have scuffed have held paint.
