My 2nd gen frame is coated in POR 15. Seems to be holding up good, but doesnt really see any street time.
powdercoat it i got a guy in dayton that does it reasonable if you are gonna keep it for awhile and want it to look good he did mine inside and out on a boxed frame pm me if you want his num.
I agree; powdercoats the only thing thats truely going to last, and compared to products like POR 15 it is'nt that much more expensive. I had mine powdercoated for around $500, and am really happy with the results...
