Does anyone else use something besides shellac to seal the knots that works
well when painted? I know Zinser makes a primer that includes shellac and
I've used it before but after a year or so, the knots still bleed through.


I used aluminum paint (spray bomb) on a stubborn corner that was
attracting mildew. Latex paint over that and it hasn't come back in 8
years. Could also use brush on from a small can.

I offer this up knowing you don't want the odor issues, even tho that
only lasted 1/2 hr indoors.
