hey everyone. i am planning on shooting some primer on my '47 this weekend. i want some sort of good primer sealer, as i plan on driving it this way all summer. but, i am not looking for anything insanely tough, as i will need to sand it down to paint next winter. i am planning on buying something from PPG as that is what my dad usually sprayed with. if anyone has any ideas as to a good quality primer to use, i would really appreciate it. someone already suggested DP-90, any thoughts?
