use touch up paint until you can save enough money to strip it down and professionally paint it or powder-coat it...spray paint looks like $hit...sorry, just expressing my opinion.
I believe a few of use had a conversation about how much powder coating cost for the sub fram and frame. None of us payed over $250 (that included sand blasting the old paint off too). Its just a lot of work taking all the parts off and putting them back on. painting on the other hand may be cheaper but not as durable (the type thats baked on in ovens) .
