Spectacular job!!!!!!!!
I was thinking about doing the same thing - went to a chrome-plating outfit where I was quoted $100 per tip, for polishing the outsides only. They wouldnt touch the insides. So, I simply sprayed them with hi-temp chrome. It doesnt look too bad, but not close to yours.
Excellent article, think Ill get started on mine (bought a spare set to work on so as to not destroy the originals).
