I've used G2 paint on my previous car too for the calipers. It's an awesome paint. It lasted awhile but some spots came off due to remounted the wheels and rubbed in the process over time. It's highly recommended not to do it when the weather is very humid.

The link is no longer active on eBay. I did find them here though,

Thanks got them. I think they will be stencilled the same colour though not like your oem looking ones...

It looks really good. I plan I doing my calipers soon when the summer heats up. I'll post up when I'm all done.
