From paint roller to rattle can paint job

Looks good. Nothing wrong with rattle can. IMHO, you do need a paint can with a fan spray pattern, and many brand name paints have those spray tips. You can get decent quality from the more traditional round spray patterns, but the fan pattern cans are best and more like a paint spray gun. Take your time and go for good coverage and overlap. Plus, Eastwood has a rattle can 2K clear that can give excellent results.
