Hello all, I'm beginning restoration of the kevlar hull for an 18 year old sea kayak. I realize that this is primarily a site for wooden boat builders, but the tech support guys at CLC suggested that I post a question on this forum, because there was so much expertise here. The kevlar hull of the kayak has lost some luster, and in some areas there are tiny pin holes and splotches of discoloration where there has been moisture intrusion over the years. The hull was originally a clear kevlar hull, and now it is somewhat dull and has splotches from moisture intrusion. My initial plan was to use Interlux Precoat Primer and White Brightsides Polyurethane to paint the hull. However, I got to thinking and wondering if I should use some coating to completely seal the hull, or would the polyurethan coating serve the purpose adequately. I also know that the polyurethane coatings are not intended for below the waterline use on boats, but have been informed by Interlux, that as long as the boat does not remain in the water for 72 hrs, that these coatings will work fine. So please inform me if there is another coating that I should/can use to completely seal the hull and make it "bullet proof" before I apply the polyurethanes? Thanks for your help.
