A quick Google search turned out this canadian (Montreal) site that lists both
Red Devil and Gillett's lye (they seem to close in February so hurry up !):

Except cleaning the drains from time to time, I use it to develop the resin on
electronic printed boards, so you may also find it in electronic stores.
As indicated, be *very* cautious with sodium hydroxyde, on the fingers you'll
find them slippery (your skin is starting to dissolve ...) and into the eyes,
you can just remain blind, so use gloves and eye protection !
In France, you can find it in supermarkets, freely available. I'm still
impressed that such a dangerous chemical is so easily available ...
