This seems to be very similar to the G2 caliper paint http://www.ppcco.com.au//kits5.htm
has anyone given the this product a go? I might try this as its very durable with a 'ceramic like finish' appearence
It seems like a very thorough product going off the instructions with all the prep stuff included http://www.ppcco.com.au//fact_sheets...aintingkit.pdf

Cton used this on his calipers.
Looked pretty good.

Highly recommended,used the silver Por-15 caliper kit myself ,with oustanding results.
TIP, after finishing job as per directions ,i sprayed the calippers with a high temp clear . now my calipers dont hold dirt or dust .
