Thin....
Nope... the actual trick to spraying a 'light' colour like white is to do lotsa coats instead of one thick one and give some time in between to let it dry. This will definitely help to reduce stone chipping to be so obvious. Also, make sure that you rim is clear from all debris and oil. use thinner, it will make wonders...
I have also personally done a couple of sets now; one is on wheel and the other is off wheel. Both has it pros and cons. But for a hassle free in terms of taking it out and later to do alignment and balancing again... i would opt to do on wheel.
The trick to get a good shine would be applying a lil thinner on a cotton cloth, rub it lightly on the sprayed area, to get the paint sparringly and smoother effect then let it dry and spray again. Ensure that your spray can nozzle is clean as well before you spray. It can cause unwanted polka dots...
Happy spraying.
