Hello
Was watching American Chopper this evening , I see things on that show
that make me cringe but I do enjoy the antics of that family, they always
refer to Pipe if they are building a frame out of Tubing etc. , this evening
they were working on a dragster bike for NAPA and when it came time to paint
the machine they said that powder coat couldn't be used because of the heat
involved would ruin the 4130 tubing , seems like a lot of engine mounts and
other A/C parts will have to be junked , would like to hear some thoughts on
this concept , as an A/C welder it is of interest to me.
Thanks

Powder coating won't hurt 4130, but is NOT RECOMMENDED for aircraft
use because it can hide developing cracks.At least that's what I've
been told.
