>I wonder why both West's and System Three recommend presealing bare wood before putting glass on? System three literature says "precoat the wood to avoid the problem of having unsealed wood soak too much epoxy,starving the wood/glass bond.Precoating doesn't use any more epoxy than the more difficult method (for experienced fiberglassers only!) and helps insure that maximum peel strength is achieved." From page 14 "The Epoxy Book".
Who is right, The manufacturer of the epoxy or the very experienced users??? What does a home builder do with conflicting methods to choose from? Kern are you out there? Lets here from the supply side
