POR is available at (at least some) Canadian Tire stores. I would expect the epoxy primer at auto body supply houses.
I prefer to apply POR outside (works fastest on warm humid days to speed the chemical reaction setup) but if I must appy indoors I try to be near the basement exhaust fan. The smell travels and penetrates the rest of the house otherwise.
When applied by brush, I don't worry much beyond wearing old clothes and gloves. If you do spatter yourself, wipe it clean with lacquer thinner before it sets or you will be wearing it until either you wear it off or you shed the layer of skin it is bonded to.

IMPORTANT - For spray application wear a good mask to keep both particles and vapours out of your lungs.
