When I installed the hatches on my SW17h I used the bungie hold down kit (modified), the stock seal and I glued in the thin rim on the hatch sill. This caused the hatch to sit proud of the deck by the amount of the rim. I spoke with Eric Schade about this and he said this rim was added by CLC and he does not use it on his builds. He also said that he rips minicel foam on his bandsaw and uses this for the seal.
I want the hatches on my wife's SW16h to be truly flush (and water tight). Does anyone else have experience with this?
