You may want to talk to Art Thraen at ACE.
Arts Web SiteI am gunna guess he can do whatever you can dream of doing on webers.
He has tweaked 2 sets of carbs for me in the past. Jake uses him exclusively.
And he knows some srious shit about carbs.
IIRC........ Ingelese used to sell carbs plated or Powder coated, I haven't looked at their site. But ya may wanna look yourself.
And there is some guy on the SAMBA doing it also for bugs and such.. (Serranos?)
Or you can disassemble em and have ot done yourself.
Or pay me huge bucks and I will do it for you.
Hope that helps..
Cheers,
Clayton
