There is no such thing as magic fairy dust, and no such thing as primer inclusive paint, in my opinion. Go to a real paint store and buy real paint appropriate to your appliation..The pros in the store should be able to help you with the project. Go to Sherwin Williams or whatever major brand paint store you like in your area. Do not go to a store where the guy behind the counter who last week could have been asking his customers if "you want fries with that?"
Prep work and quality materials are the key here. The real expense is the PITA of doing it at all. (PITA = Pain In The ***) So do it right the first time.
