sounds like bad surface prep. roughness comes from lack of sanding, dust/dirt on surface to be painted, or dust/dirt blowing around in shop or outside....or all 3 at once.So...I fail at rattlecanning. Haha.
The texture keeps ending up very rough, and I can't seem to get it to not have lines where I painted.
The hell am I doing wrong?
yes. you may want to try flat red or flat something else. it is a bit harder to find. but the stripes will be less evident.and black sucks!!!!!!!!!!!!!!!!!!
I did the entire neon with many rattlecans and its' very hard to get the right amount of paint at the right angle.
