I’ve had Jade my first build the one you passed on the way home from Cooma done in Deep Bronze Green for four years.
I didn’t use hardener and that’s how I know about the fuel issue
Ive got scratches from bushes and such but it’s only really surface the colour is still there, it does dull slightly and I do keep my cars under cover.
It does have a specific thinner for spraying but it dries quiet rapidly, I sprayed the panels on sawhorses outside.
yes I would recommend it it’s not the super glossy over the top finish that many resprays have on Series vehicles

Cheers Paul
