I picked up 5 gallons a month or so back, no problem. I’m priming drywall and my drywall is my air and vapor barrier on the inside, cz6 in S. VT.

S. Williams has something that is $80+a gallon, no thanks.

Go with a shellac kilz/etc?

Anything a little less voc heavy that will give me a good perm. #.

The 57300 claims .50 at 400 ft/gal.

Plan on top coating with 2 layers of ultra spec 500 matte or flat…

Thanks!
