OK, I did some checking. From the Kilz web site:
To block tannin stains:
KILZ Exterior, or KILZ Premium primers
KILZ Premium primer can be used as a tannin sealer and undercoater on all
types of exterior wood. NOTE: Because of the variances in wood substrates,
even multiple coats may not stop tannin or resin stains on all wood surfaces
and knots.

Even clear for interior trim to be painted gets pricy. You do have to use
some care at the big box stores though. They do have some real crap.
