Ed,
The correct name of the urethane sealant is NP-1. It's available from any  
reputable roofing supply house and Sherwin Williams has a private label brand of 
 the same thing.

The  term Life Seal Sealant was used in the discussion of leaky ports under
the  subject heading of Tangent Topping Lift Question.  Can I presume  that
the sealants correct name is Boat Life Sealant?

I tried to use  that Boat Life in the cockpit drain a couple of years ago. 
It did not hold  up.  At the direction of a professional roofer on this forum
I used  one part urethane roofing sealant.  It worked as he told me.  I  also
used it on my project boat rebuild.  The stuff works and comes in  many
colors.  The brand name Rummy referred me to was HP-1.

The  problem that the Boat Life seemed to have was adhering to the  epoxy
repair.  I had used Boat Life for years just as a sealant, but  it did not
want to stick permanently to the epoxy repair area.  That  repair was with
the West System products.  Also, the repair was made  about this time of
year, maybe a few weeks later when it was just warm  enough.  I waited until
epoxy repair was fully cured.

You might  be able to do it in one day about June 21st.
