Like any paint job the more and better the prep the better the job will turn out.
The caliper paint kit should tell you what to do and how to clean and prep.
In General:
Pull the tires, wash and degrease the calipers with soap and water, let them dry, I would hand clean the areas you are going to paint with alcohol and paper towels, tape off what you don't want painted and have at it...

You do not need to remove the calipers as you are going to paint only the visible portions, the amount of detail is up to you.

I myself used standard Rust0lum enamel paint and have not had any issues with blistering or peeling and its been about 6 months...

I brushed mine and used a 1inch brush and a small art type brush for tight areas, keep a rag handy damp with paint thinner to clean up any oops and to straighten out any detail lines

 

I agree, Thats pretty much it in black n white. I am out for uniqueness, I like to make things look good without sacraficen the way its designed to run. I would like to eventually get some headers though.

Nice job on the wheels in2pro!

 

Dupli-Color's paint is very good...just make sure to sand, prime and paint...if you don't go with the covers of course!
