I'm in the process of rebuilding a bicycle frame and am left with some
minor dings and scratches which I want to fill and fair. The tubes are
rather remarkably thin and I really do not want to use a file to clean
them up. My idea is to use lead solder as a filler and my problem is
that I have no idea what to use for flux.

The reason for using a metal filler is that the frame will eventually be
powder coated and the preparation used here is a good glass bead
blasting and I don't think that conventional painting fillers would
stand that, or the high temperature baking.

My powder coating guys tell me that they cure at around 200 degrees(C)
minimum.
