Alright ordered some clay.
But what about my original questions:
- How much wax do you guys use on your GTi's?
About as little as possible to get an even coverage. All residue is wasted product.
- How do you manage an even spread?
Wax on the applicator, small circles over a panel, finish with straight line passes from front to rear.
- Whats the best way to apply the wax?
As above
- Bumpers/side-skirts should be waxed aswell or is that a no no?
Only if painted. Avoid plastic trim
- Apply wax to glass aswell?
No.
- How long to leave on before wiping off?
Until dried to a haze and comes off easily. There should be some specific instructions on your product but about 15 mins I'd say in this warm weather.
Make sure car is out of the sun and cool before you start any of the cleaning.
