That's good to hear. The SOF I recently sold, and the one I still have in my 'fleet', both have PL Premium on them.
I have tried paint only, epoxy, fiberglass cloth with epoxy and PL Premium. The PL Premium seems to be by far the best. And it requires a lot less paint...

You might want to also post on the Kudzu Craft forum - they might be interested although in any mention of it in the past most did not seem to receptive of the idea.
