painting fastback

Hi, Going to paint my 67 fastback and trying to figure out how much paint I need , I bought a gallon of primer from tcp global and want to buy single stage urethane paint , I need to spray the engine bay, hood underside trunk compartment and lid underside plus door jambs and door edge and bottom, first car I ever painted so am probably going to use more than a pro from what I have read , was told a gallon but I was thinking I need 2 , anyone have any knowledge on the amount I need, Thanks
Maybe some guys could do all that with one gallon, but I doubt it. I have had professional painters tell me that they could paint a whole car with a quart of paint. I say BS. You want to have plenty of good coverage, and you won't get that by trying to stretch one gallon out for the whole car.
When I painted my car, I bought my paint from TCP Global. I like their paint. I have used it a lot. It sprays as nice, covers as nice and polishes out as nice as any name brand paint I have ever used. Anyway, I bought 2 gallons. I painted pretty much everything like you are planning to do. I wound up using all but about a quart. I like having some left over. That way, if you need to paint a door or fender at some point in the future, you will have exact matching paint to use. I had to paint my hood a while back, and I was thankful to have that left over paint. I got an exact match. It is also handy for touching up chips and scratches.
Here is an example of TCP Global paint. If you have any questions on body work, priming or painting ask here on the forum or feel free to PM me.
