Soooo.... this weekend I think I might get around to spraypainting the inside of my HAF 922. I have two cans of Matt Black paint and one can of self etching primer. I take it I should just be sanding the inside down roughly, putting one or two coats of the self etching primer on, giving them an hour to dry in between and then starting with my black coats? I'm just after some advice for not messing it up, such as how long should I leave it between coats, as it is the first time I will ever have really spray painted anything . (And I will be doing it in a well ventilated room and covering everything in made amounts of masking tape I imagine ). Any tips would be much appreciated!
