I agree.Killing ALL the rust is recommend. There are all kinds of methods to do so including acids, sand blasting, and sealer paints (such as POR-15). On my seat pan I sand blasted all the rust off best I could but there was still rust flecks down into the pits in the metal. After blasting I used POR-15 paint to seal down any remaining rust. POR-15 claims you can seal over rust but I'd rather remove as much as possible before sealing just to hedge the bet.
I have done a couple of tanks with POR15 sealer and very happy with the results. Also used POR15 products (rust preventitive paint, Blackote & Glisten) on the seat base, frame, wheels and engine covers. You could say I am a bit of a fan of POR15. Has has been said by others "FOLLOW THE INSTRUCTIONS" Preparation is important.
I just painted the outside, with regular auto paint but I'm sure the POR15 rust preventative paint would give good results on the tank underside. Could use POR everywhere:dancing: but the colour range is a bit limitedI was just wondering about the outside. I have seen stuff with names like rust stop and such and always wondered if they actually stopped reaction of rust on the outer surfaces..
