After reading a good bit on the subject online, I'm contemplating trying out PL Premium for fillets inside small (under 20') stitch and glue boats. Any thoughts/experiences/cautions?

I take it that you're not going to fiberglass the seams? You can't do that over PL Premium. You're not going to get anywhere near the strength of glass/epoxy construction.

The PL Premium is worked into the fibre. Photos at www.sinmplicityboats.com. I tried PL Premium and fabric butt blocks but they were week. The cured patches broke before the wood spilt. Seam fillets would be thicker and stronger. David Beede's tests look convincing. -- ------------------------------------------------------------------------------ William R Watt National Capital FreeNet Ottawa's free community network homepage: www.ncf.ca/~ag384/top.htm warning: non-FreeNet email must have "notspam" in subject or it's returned

I should add that plywood butt blocks held on with PL Premium using weigths during curing have shown no indication of letting go. Also 1/2 inch thick spruce skids attached to the outside bottom with PL Premium, using the temporary wood screw technique for curing, are doing fine.
These are lightweight 11 and 12 foot plywood boats stored indoors over the winter.
I've used the ordinary PL Premium, not the cement bonding type D Beede is trying.
