just noticed you said polyurethane, so you probably meant this product:
http://www.homedepot.com/p/Loctite-PL-Premium-28-fl-oz-Polyurethane-Construction-Adhesive-1390594/202020474
which works out to 4.01 FL oz per dollar which is not too bad, not as good as the other two products, but if it really works that much better it could be worth the extra money.
I appreciate your input and with 35 years in construction business im sure youve tried them all, is the one I linked above the one you are talking about? If so that's what I will pick up.
Thank you.
