What to use to protect bare metal during extended body work

[Blown&Injected]

Planing on doing lots of body work and some of the paint is checked so it will be going to bare metal on several large areas. So what do I do to keep it good until ready for paint?

Primer? Sealer? self etching stuff?

I am hoping there is a good coating that can be sprayed from a can that will keep it good and not need to be removed so that I can continue from there when it comes time to start the paint job.

Thanks

Ive had good luck with a daily dose of WD-40. Flash rust/surface rust is usually prety easy to get off if you are carefull.

I used $1 Wal-Mart rattle can primer and the car sat out in the weather for over 6 months - No Problem!

Use a primer.I think there is differnt primers if it is going to be outside in weather.I will ask my painter what to use.

Acid etch, not from a spray can. There is a difference. Do not use spray can primer, or oil. Unless you want it to look like crap in a year.

Thanks for the ideas - if I have to mix and spray from a cup gun I may as well use a good epoxy primer/sealer and paint the part too - I'll paint it like Johnny Cash built his Psyco Billy Cadillac

Epoxy is old tech. Use an acid etch.

Our process...

After stripping w/ media blasting, etc, we use "A MUST FOR RUST". It's a spray bottle, like windex, & is sold at Home Depot. There are several products, for different applications, so look closely at the labels. About $8.00/qt.
We mist a LIGHT coat on, scrub in with a Scotchbrite pad, and let it dry.[A qt will treat a BIG car!!]
NOTE: this product has a mild acid etching chemical in it. Use rubber gloves, and do not spray on a painted surface.
As a prep for such work, we ALWAYS go over the surface to be worked, with an 80 grit, on a DA, then apply the inhibitor.
Once you are ready to work the area, take the DA, and go over the areas. The inhibitor will dust up. Blow dry, wipe with Prepsol [wax/grease remover], and get r done.

Works well on $150K street rods, so should be good for most any application.
