303 protectant on tires before or after Tire Wet?

Because it's useless for tire preservation.

Tire wet is for "looks". It makes it look wet, and repels water - the latter is hardly an important feature for rubber.

303 provides UV protection - VERY important for prolonged exposure in hot climates, and it also repels water.

I'm aware of that which is why I'm asking about using both.
