take everything off: i.e. wheels, cranks/sprocket/chain, bars/forks, and remember to cover up your BB bearings and headset bearings. and dont forget to sand your frame down first. all you really need to do.
I painted some stuff using Krylon fusion and that stuff is great. Just sand the stuff with 400 grit sand paper and do a coat of paint every 5 minutes for like 5 times. You will be satisfied, beleive me. You can get the paint at Wally world
NO you want to buy a RED SCUFF PAD (if the paint is decent if not strip it down and sand the rust off) and some self etching primer! take everything off the bike and scuff the whole thing then dust in the self etching primer... You wasnt KRYLON Flat black BBQ paint or Flat black engine paint! this turns out the best... Buy 600+ grit paper and slowly sand down rough spots in between coats.
Stripped and sanded:
Think i might make a decent how to the next time im painting
*spray paint is not spraypaint* The hightemp and auto stuff holds up better if krylon BBQ is durable and flat.
