This is just FYI.

I have tried alot of different wax's and sealants (including Zaino, Classe', S100, etc) on my white GT. I am always looking for the deepest / wettest shine, and white is a tough color to get those results.

I have found a combo that looks VERY wet - even in sunlight yet has some depth to it.
Here is what I used:
Step 1: wash car Zaino car wash
Step 2: Clay finish Zaino claybar
Step 3: Wash again Zaino car wash
Step 4: Poor Boys Polish w/ carnuba applied w/ Porter Cable orbital - white pad
Step 5: Clearcote Vanilla Moose - Porter Cable orbital - white pad
Step 6: Poorboys EX-P - Porter Cable orbital - grey pad
Step 7: Poorboys Carnuba Moose wax Porter Cable orbital - red pad
For me there is none wetter, deeper, or shinier. This combo rocks on white.

I'll post pics from outdoors soon. Any finish will shine in the garage or in low light.

 

Now top it with Zaino Clear Seal!

 

is that a yellow RX-8 in the reflection?
