I have an old schwinn Madison frame that I want to get powdercoated but it has two small dings on the top tube. Would I be able to use some brass Braze to fill the dings then file then smooth? Would it be possible to do this with a cheap mapp torch? I don't have the materials to do it because I want to be sure of the stuff I needed to get. I asked here because it was a question about brazing! Sorry if it's in the wrong place!
