Any update on this? it looks a fantastic shine on the bonnet pic and like you said more coats will only give more paint depth to work with when flatting and polishing, I'm looking to use the exact same brand paint when I finish the panel work 1st.
I was originally thinking of spraying due to I'm told its less work to get flat (as long as you don't get runs!) but a roller would be far less mess and I don't mind the extra work.
hope you are still at it and haven't given up on the project as it was looking great!
