I am planning on painting my calipers over thanksgiving break so i'm trying to gather all the items i need so i can get to work right away once the break starts. I am wondering if i can find VHT break cleaner and VHT caliper paint locally like at walmart or autozone or something, or is it only available online because not many people use it? Also is 1 spray can enough for all 4 calipers? Thanks in advance
