memdonjo, a fellow bolter,Swradial, turned me on to a little trick several years ago. Stand your boards up on their ends in some of the product your using and let the ends soak over night. I used the helmsman spar urethane in 1999 and it works good. It does stay inside most of the time but it has seen its share of rain..... then, about two years ago, I refinished mine and did like Tim, SWraidal, suggested and the same boards look nice today. Just SOAK those ends.
