I’ve always used Benjamin Moore Fresh Start Alkyd exterior primer to back-prime and prime end grain on my exterior trim. Problem is that it really has to dry overnight before handling which seriously saps my productivity.
I’m looking for a primer that will dry more quickly (1 hour) in these applications.
My paint supplier sold me a can of Zinnser Cover Stain oil-base interior/exterior primer that claims to dry in one hour. Is this an appropriate primer for my appications?
Thanks!

What did your paint supplier tell you? He is the one who should know. Likewise, you could also call tech support at Zinzer.
YMMV

Zehrung - Z Prime Plus - good stuff
i'd look on label of that 123 - does it stop cedar tannins bleed through
You'll need ot be careful if you use a shellac based primer for exterior work. Shellac gets soft when it gets hot. And it will get hot under sunlight if the topcoats are a dark color.I'll be that if you read the label on Zinser's white shellac, it will say that it should only be used as a spot primer in exterior applications.Politics is the antithesis of problem solving.
The OP was talking about backpriming and end grain after cuts.
As you say, just spot prime for exteior work.Chuck Slive, work, build, ...better with wood
90% of the time we use a BenMoore product.......primer is just what you use
for touch up and cold weather we use the Ben Moore exterior fast dry primer
