yeh I had a bit more of a look around and it's not worth it for 2 pac if it's going to come off - they're asking $250+ for primer, 500ml of paint and clear... phoa

So had a look around and found a brand called VHT http://www.speco.com.au/vht_wheel.html which is specially made for calipers and goes up to 482 degree C! Once you paint them tho, you have to bake them in ur oven for about 20mins at 100 degrees to get the full curing...

And best part is they come in gold too lol + you can buy the primer and clear with it - from like Supercheap or Auto One.. so I think I'll be checking that out...
