Eastwood epoxy primer

Maybe overkill maybe not, but I use the epoxy with some reducer as a sealer. The job is epoxy primer, then high build urethane primer, IF pitted metal I will use some polyester primer if needed, then a reduced epoxy as a sealer, then topcoat. I am maybe a little anal!?
I want no rust, as straight as my 71 year old body will allow, a decent topcoat,. IF not perfect I care less, I will drive it and it is just a hunk of metal, nothing rare!!!
