For a Tire Spray, I use -->
Stoners More Shine Less Time. I just tried it a few weeks ago. It's so quick and easy as it's an aerosol spray versus a pump so you just hold down the nozzle in one go and spray around and it's easy to control. You just spray and walk away as it says. This stuff is nice and cheap too.
For a Tire Gel, I use DP Gloss Tire Gel. DP products are excellent value.
