There are no west marine stores in my area. So called around to all the local marine stores. Most of them thought i was crack. They never heard of those.I'm looking for those fillable caulk tubes. I need to put epoxy resin in some holes and where my transom wood lays against the bottom of the hull. My transom wood doesn't make full contact with the hull. And i thought that would work prety slick for doing the fillets.
