Plumber's Goop Equivalent Where to Buy Please ?

Coming to the end of the school holidays, I need to repair the ravages of fierce games of Sharktopus, Sharks, Crocodiles and turtles on inflatables.

I always lose these encounters as it seems that "Rules Change"....see Bill Maher is universal.

Youtube shows many fixes and Plumber's Goop seems excellent.

I have difficulty in explaining at the usual outlets, any help please ?

Thank You

Hardware House on Sukhumvit Road almost opposite Ambassador City. As you walk in from the front, pass the cashier points and paints, you will find it 4-6 rows down on right.

Thanks very much, virtually across the road for me.
