The SEM trim black in quart/gallon form needs to be reduced with their reducer 1:1. I would start with SEM's gun recommendations, and you may need to tweak from there. Test on some paper or scrap before attempting on the vehicle. Holding the gun far away may end up getting you some slight texture. You will definitely be faster to R&R the hood. Less chance of getting overspray on the car, because even masked off you will find some somewhere...paint manages to get to the most crazy places. For materials any paint shop should have paper, tape and fine line tape for the edges. Home depot stuff won't do the job for this one.
