Hi @stevoggo – I checked the MSDS for Aquaseal and it looks like the main ingredient is 4,4′-methylenediphenyl diisocyanate, with toluene as a solvent. Shoe Goo is tetrachloroethylene and styrene, 1,3-butadiene polymer. So, not the same thing, but that doesn’t necessarily mean it won’t work just as well – the only way to know for sure would be to test them side by side.
This thread seems to have some good info from people in Australia, so give it a look: https://www.seabreeze.com.au/forums/Kitesurfing/General/What-brand-of-PU-Glue-do-you-use?page=1
