Just checked and I used Valspar Alkyd Enamel Hardener with my bumpers (anvil gray from Jim Carter),
Like others said cover up with a paper paint coverall, gloves taped over the coveralls and wear at least a P95 respirator that you can buy at harbor freight for about 16 bucks or less with a 20% coupon. They will protect you from the isocyanates in the hardeners. Oh I used the hardener at 8parts paint to 1 part hardener. You will be just peachy.
