any products here in canada? alot of stuff like this we cant get; im going to check my electronics store after christmas for somthing like this!!!
You could, but it would be kind of a waste of the expensive shielding paint. The SuperShield will bond to bare wood, but it will tend to sink in and be rough, particularly on end grain, like the side walls of the cavities. You'd have to put on more coats to get it to fill the grain to the surface, as you would with most paints. Why waste the SuperShield doing that?
In my painting process, I start off with 8-12 coats of clear base/sealer (Target EM1000), with dry sanding between groups of coats, to get all the surfaces fully sealed and leveled. That's a fairly messy part of the process. When that's done and the body is all smooth and cleaned off, then I spray the two coats of SuperShield to turn the cavity into a conductive shell. The SuperShield bonds easily to the smooth base paint. If a bit of the SuperShield bleeds under the edges of the plywood masking template in a few spots, I can clean it up with a touch of sanding. Then I mask the control cavity (with an aluminum plate that screws down in place of the control plate) and start spraying the color coats.
You should be able to find a supplier in Canada. Mouser Electronics carries it. I just noticed that it's even listed on Amazon: http://www.amazon.com/MG-Chemicals-C.../dp/B005T8O7X4
Here's MG Chemicals' own web site listing of it, with all the technical info: http://www.mgchemicals.com/products/...ld-nickel-841/
I hadn't noticed it before, but they are saying that the base paint is a low-VOC acrylic, not a polyurethane.
MG also offers shielding paint in Graphite, copper, and high-purity Silver. In case you want your basses to be shielded against extreme frequencies....
