If you are sold on the rustoleum safety red color, my best recommendation for that is to use the John Deere Fast Dry Thinner, Use the 5star Hardener, along with their paint. IMO that is going to give you the best finish with the rustoleum products.
Red Paint is the most expensive color ever, if you are going with the single stage enamels, you need their proper hardeners, and reducers to go with them too, product specific stuff. You are going to be right at 500.00 as a starting point for the single stage paint system in red.
Lots of things to do to the car yet, can get the body work done, get it in full primer and see where you are at at that time.
