Ha folks,I was going through the forum an noticed some people said there LBS was "rust proofing" their steel frames before assembly or delivery.
What is this? and What should I expect them to do?
It means they are having the inside of the frame tubing (which is where most problematic rust occurs) treated with a product that will leave a residual coating, preventing rust. Probably the best and most popular product for this is called "Frame Saver," it's made especially for this-
hey, can this be done retrospectively or does enough gunk build up inside once you've had the frame a while to render it less effective?
Framesaver says it's ok to apply over light rust. Personally I would get rid of the rust first by soaking the frame and fork in a solution of oxalic acid (aka wood bleach), since you can't see how bad the rust may be in the nooks and crannies of a frame. Either route you take you will need to strip the bike down first since the Framesaver leaves behind a waxy residue that would gum up your bearings otherwise.
