I have the clear lacque (I got it with the Paint stick set for the car color (silver)), but I didn't use it for the wheels (although it came to my mind)
It would certainly help the durability of the paint on the wheels, but I think that if I painted the wheel with the clear lacque (after the wheel paint), it would be more visible and worse then scrachted and nonpainted...
I wanted to try the clear lacque on the small part of scratch, but just didn't have time to play with it...
Oh I forgot to explain how my wheels got scratched... (both driver's side wheels) - I got them scratched on the brand new car from the HPC (Germany), but I noticed it when I came home and washed the car for the first time...
Guess why - cause they painted the scratch with their stick too!!!
So actually they were aware that the wheel was scratched but they painted it and hoped that I will not notice it when picking up the car - and they were right, I didn't notice it...I was too excited.
