321. 3 parts mineral spirits 2 parts oil base poly 1 part BLO. Dries pretty fast has a slight odor that doesn't last long. Semi gloss finish. You can use other mixtures. I really like it.
My garage is well insulated too. Drywall and all. I insulated the doors with fiberglass. It definitely gets hot. I only have a fan too I deal with it as long as I can then I go back inside.
I never realized it but you can resize a pattern in Gimp 2 to print it. I always had rapid resizer but don't have the money for it right now. I don't know if anyone else knew it but hope it helps.
