[Roadsters] Brake rotors

[Embarq Customer]

I had a client that developed a procedure called flame spray deposition or something like that.  He had a plasma gun with a metal wire feeder like a mig welder.  Compressed air would blow the molten metal out kind of like a sand blaster.  The molten metal would stick like welding flash only in tiny particles.  He could build up parts like heads that were cut too thin, engine blocks, or brake rotors.  He could also deposit zinc on steel to make a galvanized coating on existing structures like bridges.  I thought it was kind of a neat process.  I've heard of a similar process used by the navy on ships.

This just occurred to me - and I'm surprised that I haven't run across
it before: Are brake discs repairable by surface buildup weld repair and
regrinding? I can foresee potential problems with this - warping especially -
but maybe this is not an insurmountable obstacle? 

I have seen some pretty beat-up crankshafts welded and reground, but this
thread on brake rotors made me realize that I have never heard of this being
done to brake discs.
