My deal is I'm switching from an aluminum frame to steel (i.e. new bike, bought just before the old frame broke on me). I live out in farmland and the drainage is "by nature's design", so a big rain means flooded roads. Last year I submerged my BB three times and one of those got both hubs too, so treating the frame seems like a good idea.
For some reason I thought Weigle's Frame Saver was no longer available. I must have been thinking of something else.
