aquaseal has held many a pair togerther for me that would have otherwise ended up in the trash...I have recoated entire seams, boots cracks, holes, rips,ect. I have one pair that is mainly aqualseal waders now
Seriously, good stuff and it should be in your truck. It takes a while to get hard if it is humid but it seals up problems. (need to try the window roll up thing)
I ususally pick it up in tackle shops.
As mentioned above...for bigger rips you should patch it on the inside as well, the wader manufacter usually gives you a hunk of material (look in your original box) to use for such problems.
For little holes and cracks, just dab some aquaseal on it and let it dry...like new.
I like to let it cure for 24 hours before using it again.
