Wheels, MarineTex is the brand of epoxy
"paste" sold pretty much universally in chadleries in the US. A small pot of goo about the thickness of peanut butter and a small bottle of hardener, sold in black/white/gray IIRC. It isn't a putty. JB Weld is another brand sold in automotive stores (two tubes, each like toothpaste, final product gray) and PC-7 is a true paste sold in two small tins (35mm film cans, one fluffy the other like tar) in hardware
The stuff that comes in rolls, with one part in the center and the other wrapped around it, is called "plumbers epoxy" in the US. Sold in plumbing
stores under many brand names and used among other things by plumbers to seal small leaks
. Any and all of those brand names forms a permanent repair, I've got an old soldering gun repaired with PC-7 30++ years ago, no sign of it failing yet.
