Hey David, I might need some painting advise in a couple of months. 
I can help you out with painting advice . . .
1) Don't try to get of a paint job cheap . . . spend an extra dollar per can and get Krylon.
2) Don't try to paint if the wind is blowing more than 10 mph.
3) Don't paint if it's raining.
4) If you want a really slick finish, wipe the chucks of the dirt and any big bugs off of it first.
5) If you have rust spots, tap it a time or two with a rubber hammer to knock the loose stuff off and coat it good with rusty metal primer.
I've got a couple dozen more paint tricks, but I don't want to share all of them . . . :lol:
