Congrats, this looks like a fun build! No hesitating at all...LOVE IT! Ive used the evap-o-rust its amazing eh?? If Canadian tire is out of it, try Home Hardware, they carry it as well.
PG classics and BE&A are the same company. PG covers Canada and BE&A covers the US. Try to order from PG it will at least probably save you on shipping??
Classic Industries I have read are pretty good as well..
