Last I heard, Ed Begg, V-Bull precision was the Canadian guy for K-G.
Gunkote (and GearKote) are great products.
Just spoke to a guy at http://bitsofpieces.com
They deal with GunKote.
Yep, Barry is a good guy and has done a Gunkote job for me a couple years ago.
The person on the phone quoted $150 for the Glock slide work - this is exactly double compared to what is charged in States.
