Found a decent patch kit at a pool place in Wynberg if you're in the Cape. Otherwise duct tape kept my pool from leaking for like 2 months - and it wasn't a small hole. (turns out it sticks underwater. Still not convinced the patch kit is better, but at least the colour matches. Black tape in your pool does not look nice)
The kit instructions say you can stick inside or out. I have one patch outside and a few inside. Stuck them on with water in the pool. Messy but it worked. Took some getting used to.
Yep in the cape so pls send me the details of the place in wynberg. Drive past there every other day.
