Rusty seat pan fix

[Guest]

I have a seat pan here to replace the one on the bike that is falling apart. The "new" one has rust on it and I am wondering what to do to it before recovering to keep it from rusting further.
Just a coat or two of primer? Or a wire brush and primer? Or something else?

Sandblast off the rust and prime with Por-15 paint. If using Por-15 you could even get away with using a wire wheel, although I prefer sandbalsting.

I just used a wire brush and rust convertor on mine.

Started like this:



Rust convertor did this:



The rust convertor etches it nicely for paint too, and I brushed on POR 15 Blackcote as that's what I had handy:



Having said all that, sand blasting is probably a better idea, and the POR 15 Ed's talking about is also a better idea as it rust proof's the pan.

What I did was use the rust convertor to get rid of the rust that was there (90% of the rust was just surface rust) and I then used the Blackcote just to prevent moisture getting at it again, but it probably won't last as long as a properly prepared POR 15 rust proofed pan.
