Hi, I need to know how this stuff works. If someone welded a crack in a frame and then re-heatreated it, would it make the frame more brittle and likely to snap/crack in future. Also would having the frame heattreated again mess up a paintjob? Is it even possible to re heat treat a frame? One more thing, how will a frame last if a crack is just welded back up? cheers, george. p.s. if it makes any difference the frame in question is an es3 with a sparkly black respray.
