Try Mayfair Plating in Toronto https://plus.google.com/104553983973643 ... l=uk&hl=en
. there is a few around. Consensus is cosst vary between companies from $75-125 for blast and paint depending on color.
Tried looking up this place but can't find much info. I see they work with metal but looks to be more chroming finishes as opposed to anything else. No mention of stripping or painting, although they must know a thing or two about prepping metal surfaces.
Did you use to live in Toronto and made use of their services?
No Im born and bred in the UK. After reading your post I had a scour through the web and found a post where someone had used them for bike frames.
