i been using Rustoleom for many years with no problem. use the same brand primer and you will be all right. they big cans so shake new cans 3 minuets by the clock. if using the next day 2 minuets. if let set over a day i always go back to my 3 minuets. if you in a cold weather zone and dont have a hobby room set up with a spray booth set the can in warm water for 10 minuets to warm the paint up. they are a lot of people are gonna trash talk Rustoleom paint but if that's what you want to use its your choice. i just told you how i do it..
