Bill,

I used bathtub calk sealant (white) on my Lancair 320.  It works really well.  You need to mask off either edge of the seam with painters tape.  Remove the tape before the calking has a chance to dry.  The calk will discolor with dirt somewhat as the months go by.  I now also use a layer of sailplane white anti-peel tape over the top of the calk after it dries although it peels off at the leading edge after a while though its easily replaced.  I can come over this weekend and help you if you like.
