After reading about drill-fill-drill and envisioning pounding a zillion brads through rub rails, through the epoxy, through the fiberglass, into the sealed up boat, I stopped and wondered, WHY?
Since when does a kayak need rub rails?
Why penetrate the hull with all those brads and provide a conduit for potential water seepage straight into the wood?
Instead, I decided to use my rub-rails as a topper for the cockpit combing. I didn't like the idea of exposed end-grain, without fiberglass, in an area that was sure to get wear and tear.
