Hey guys, I dipped a set of valve covers and used 2k clear but the rough cast aluminium looks pretty terrible. I sand blasted them but they were just pretty rough from where they were cast and I use a pretty fine grit media. I did 3 pretty thick coats but still not close to covering the roughness and just to make it a little more difficult I flash cured them hoping it might come out decent. So now I dont think I can rough it up to add more clear due to bumps I think It will go through the clear and graphic in those areas just wondering if anyone has tried a clear powder over a 2k automotive clear. I think a couple thick coats of powder might make them look a little better. Thanks for any advice.
