Scooping the Goop

Saturday was really one of the less fun projects I've undertaken.  The goal was to scoop as much of the old butyl goo from the deck-to-hull joint as possible.  I say "as possible" because unless you can lift the deck right off, there's just no way to get it 100% clean.  

I used a small thin pry bar to lift the deck, then reefed out  what I could with a putty knife.  Avery foot or two I'd then go back with a rag soaked in mineral spirits and clean the residue.

It took me about 2/3 of the day to do one side.  Spending the day on a ladder muscling a small putty knife is not as much fan as...  Sailing!  But it's necessary.  The joint was leaking for sure, and about 75% of the butyl had lost its normal nasty tackiness.  I hope I never take the toe rails off again, so I'm trying to do it right this one time.

Still working out what the replacement goo will be.  I was thinking I'd use butyl again, but there's just no way I can lay the tape in there; the slot is too thin.  I am pretty sure I can rig a narrow tube on a caulk tube though and squirt some in, then spread it like butter with a putty knife.

The choices are down to 3m 4200, SikaFlex 291, and SikaFlex 295.  I'm almost set to use 4200 just because it's available everywhere and I know it will work.  To use Sika I need to order the tubes from Jamestown or Defender.  I'm running out of time and need to make a decision soon.
