I am restoring a Euro BMW 635 CSi front bumper with limited success. I would like to remove the rusty, heavy crash bar as indicated with the yellow arrows without damaging the surrounding thin gauge metal of the actual bumper.
I've tried my angle grinder and can only get about half way through then it bottoms out. I've tried my die grinder (same story) and I've also tried using a really small metal cut off wheel on my Dremel to cut the welds off with limited success.
If I heat it, it will warp the metal, so that's not an option. What other tool options are available?
Thanks and looking forward to reading your replies,
Yasin
