My forward hatch was leaking from the frame. The lens was good.
I dug out the frame (not a quick or easy job), removed the old butyl tape, cleaned up the surface and rebedded with new butyl tape and have had no leaks since then. Note that if you lay down the tape and accidently step on it you will be digging butyl tape out of the non-skid for some time. Not that I did that.....just saying.

Had to remove the entire hatch, including frame, clean out the dried out butyl tape (or whatever the grey putty stuff was that the factory used, and rebed with Bomar hatch tape. That?s a foam tape impregnated with some kind of sealant. The hatch itself hasn?t leaked in over 20 years of ownership and the Bomar tape is now over 15 years old with no leaks. Good stuff.
