Polyurea Application

You may want to start by looking at 3M, Bostik, or LocTite. I have used 3M's 5200 Marine One part Polyurethane for most of the repairs on my boat. It provides a permanent, flexible seal that will stand up to some very nasty conditions. It is available in caulking tubes and you can find it at most Home Depots for around $12 a tube. I'm sure in larger quantities there is a significant price break. The other manufactures offer similar products. It would be worth a couple of minutes to call their Application Engineers and see what they have to offer.

Good Luck!

May I offer a couple of suggestions. Be sure to use an interlocking method of joining the panels.This will provide for expansion and contraction of the panels caused by temperature changes, and prevents water entering should a crack or split occur in the joint. Prime the joining edges before applying the sealant to maximize the bonding between the sealant and polyurea. You may investigate using a silicon sealant which has sufficient tensile strength to withstand the stress of the panels in contraction, and has a better UV rating than urethane sealants. Texas A&M University Physical Plant has 30 years experience with installing and maintaining urethane roofs. Contact Mr. Sam Cohen, Texas A&M Physical Plant for expert advice.
