Hi, i have a black pc case, the paint is a bit rough, not completely smooth. I used paper tape for masking to make a rog logo, then i painted using a spray paint can. I did it before on my brother's pc case and it was good, but this time i screwed up. Now im looking for a way to remove the paint without ruining the black paint of the case. The paint i used wasn't very strong, i can remove it with my nails but it would take forever. Also, was i supposed to use an aerograph?
