I've primered with Zero grey, several coats and light sanding with Tamiya 1500
then 3 coats of Zero Pagini Red
then 2 coats of Zero Smoke (transparent black)
then 1 mist, and 1 wet coat of Zero 2K diamond clear.
It's probably my best finish yet, but far from flawless... a bit of dust & pitting on the bonnet, will need to be sanded
