Wheel Worry - puncture problems?

During many decades of motoring I have had a few punctures and so have always had a spare wheel/tyre in the boot of my cars.


I am looking at tyre weld options.

One type is water based and claims is cleaner/better for the tyre when a proper repair is done.

Tother says that ware based repair canisters cause a problem with the tracking!

Who's right?
What's the best solution (no pun intended!)?
