Capital Auto Paints. (but I'm in Canberra)
Not sure about the heat resistant issue myself. Could be interesting.
Just make sure Autobarn get it right, as I said before, I tried them but their version of KN6 (Dark Grey Pearl) was vastly different to that done by a paint Pro. Was a nice colour but was not right.
(sorry, I missed the Triken bit, thought AutoBurn were gonna do you for $180 worth of paint) Lol.
