When it comes to this onlay (inlay) stuff it seems that some people are reluctant to tell how they do it, or think it should be done. Actually I think there is not a definitive method of application yet....though I do believe it should go under your fiberglass. If that means waiting a few days, I would. I'm interested in the hybrid method and plan on trying it later...but considering all the designs I want to build I may kick the bucket before I get there. Nice boat. Keep us posted as to what you do.
