help and options highly needed on single stage

napa paints I'm wondering if our napa does that I'm now talking to the guy that told me he has 30yrs exp in bodywork and he didn't knock the idea of using tractor fleet primer and paint then adding the dye to the tractor single stage white or so on. i am just wondering ...........i have some decent eqt i would say its a red binks m1g hvlp/2hp 10gallon compressor i used to shoot a car before but had orange peel all over i am determined just worried

i can get nassin at 300 bucks for paint primer and everything else needed not including tape etc.

anyone ever used the 50 dollar a gallon rust destroyer primer before i says guaranteed for 5 years no rust it comes like house paint ready to spray or brush it says.
