What color is that on the frame?
It's been treated with this stuff:
Birchwood Casey Perma BlueLooks rad! How long did it take you to treat the frame? I've always been curious how it holds up as well.
It took me a good few hours to get done as I could only treat a little bit at a time. You're not supposed to leave the stuff on there for more than 30 or 60 seconds so it doesn't give you much time to cover a lot of area.
Not sure how well it holds up since I only just started riding it. But you can always touch it up with some more of the perma blue stuff at any time.
FYI: The frame will still be susceptible to surface rust unless you clear coat it or rub it down with some rust protection stuff.
