Bumping an old thread, but I'm in the midst of painting a large amount of tanks. I've painted all my previous tank with the krylon spray, and it simply does the job, spray from a distance and multiple layers. But is it more cost efficient and faster to use a roll on latex paint or do you notice the brush stroke from the roller. I know from far away it wouldn't matter, but from close up it may bother my perfectionist side.
Also I don't think I want to spend time in the weather to spray multiple layers onto the tank.
