I am just about ready to prime my firewall and dash in my truck. I shaved them bothe and jst bout go the filler finshed up. I was goingto use epoxy primer and wet and it before shooting the paint (I am going to use acylic enamel). How many grade is there of epoxy primer? and which would work the best with that kind of paint?

Epoxy generally does not sand very well. Id use a urethane filler primer. Most dry in 1-3 hours. It will fill the pinholes and sand scratches in your mudwork and sands very well. Try and stick with the same brand as the paint, just to be safe...

There are two grades of expoxy primer - two-part epoxy primers and one-part primers that claim to be epoxy primers :) Otherwise any quality brand is good paint and there are some great choices out there.

As long as you stick in the same paint line and read the datasheets, you'll be fine - start with the topcoat data sheet and work your way down. Make sure that whatever you're going to prime with is OK over filler.

DuPont makes a great sandable epoxy primer, PPG's DLPF can't be sanded. In either case, you could:


- Prime with a good etching primer to provide a great foundation - may not be able to apply this over your filler, so check first If not, skip it.
- Prime with epoxy primer to provide a bulletproof corrosion base
- Surface with a good surfacer to make it smooth
- Sand for 100 years or until your hands bleed - whatever comes first :)
- Topcoat

I am going to prime the fire wall, dash and rockers/inner rockers os the majority of the priming is not going to be the in the weather. Plus I'm not gonna drive my truck in the rain or in the winter. So about the only thing that would really need a seal that epoxy prime can provide would be the rockers, how durable and how well does urethane primer seal metal?
