I can imagine that your boat shelter might trap some fumes, but I cannot thing of any other disadvantage. You have a great 'workshop'!

My Jib track is 4' long. You do not need the full 4', but I wanted to avoid using the ends. I highly recommend the set-up. It has worked beautifully with my sail. Pointing ability increased dramatically with the ability to trim properly.

I spoke with the putty folks - and as it turns out, they have no suppliers out west. It is hazardous material, so shipping was almost as much as the product... So I may en-up mixing my own putty after all...
