And also, how long does a caliper itself last?

Thanks.

 

For paint, i'm not sure. It depends what paint you use though. As for calipers, they last almost forever. Well the seals and guides can get worn out. I would say 100,000miles is a good guess (probably could easily go 200,000miles).

 

depends on the paint you get if you get them powder coated it will last a really long time but high quality paints can last a long time too. Also how good of a job applying it makes a difference.
