I'm painting a bathroom soon. There are two problem areas I want to make sure I get prepped right.
First, above the shower, there is a metal dry-wall corner that's rusting through some nicked paint in a few places. At this point, it's just minor rust stains on white ceiling paint but I want to prevent the stains from coming back and make sure the metal doesn't rust out. What's the best way to seal it in?
Second, there's a area across from the sink where over spray from hair products lands. Do I need to clean is really well before repainting? If so, what's best? I've heard of TSP being use for thorough paint prep but I'd usually use alcohol to remove hair spray. What's the best paint or finish to use to make cleaning up the hair spray easiest in the future?
