The wood finish test included two samples with Pelucid topcoated with Helmsman. They performed the best of the clear type coatings we tested, although there was evidence of failure in about a year. http://www.mar-k.com/wood_finish_testing_ii.aspx

I checked the black painted samples today and they are still without failure after 8 years exposure to Oklahoma weather 24/7.
