Sampson,

I'm certain that some of our Paint Guru's will chime in here, and if you do a Search you should find a bunch of information, but the generally accepted rule around here if you are going to strip the car is to use a Wax and Grease Remover and spray some Epoxy Primer on the car, then apply your Bondo-why? So that if moisture should somehow find it's way behind the Bondo it won't rust-as far as flex additive, there are those here who think it's Snake Oil-

There are two schools of thought about this (like you needed something else to consider ). Some advocate priming bare metal first then doing body work on top of the primer. Others say do the body work on bare metal then prime. IMO both work equally well. Old school says body work on bare metal then prime. My thinking is that whatever you do once you strip down to bare metal epoxy prime with SPI self etching epoxy first.

Save yourself some time and money..... Bare metal, epoxy prime, body work, 2K high fill primer, block sand, sealer, top coats.

Etching primer is a waste of money and time. If the bare metal is sanded, the epoxy has plenty of tooth to adhere.

remember: Etching primer does just that... etch the metal. If the metal is already etched from the sanding, why etch again?

Some people claim that etching primer prevents rust.

What causes rust? Oxygen!!! if you seal the metal under epoxy, Oxygen can't get to it to rust it. So why spend the extra money on another product.

You can spend money on Epoxy Primer which also works as Sealer. Two products in one. That's why it's labeled, Epoxy Primer/Sealer.

So we go to the paint store and we buy:

Etching Primer plus Activator
Epoxy Primer Plus Activator
2K High Fill Primer plus Activator
Sealer plus Activator
Top Coats

Or:

Epoxy Primer/Sealer plus Activator
2k High Fill Primer Plus Activator
Top Coats

So which list do you want to use? The long one or the short one?
