I've painted a couple of my frames but they are not very durable. I like to mold my frames so powdercoating is not really an option. I started thinking about spray on truck bedliner for it's durability and acually saw a bike frame painted with it and it looked pretty cool but I would like a glossy finish. I found a product called POR-15. Its a high gloss and very durable and can be sprayed on for a nice finish. What do you think? They also make a tank seal kit I'd like to try... F.T.F
