Bare Metal Protection

[Jimmy]

So I'm getting ready to sandblast my car down to the bare metal, and my painter would prefer that I deliver the car to him that way, but my concern is how to keep the metal from rusting. Here in West Texas we don't have high humidity, but still I believe some flash rusting will occur. Is there something I can treat the bare metal with in order to keep this rusting from occuring, yet keep my painter happy by having the car in bare metal?

Never tried a whole car but I used eastwoods metal wash on panels as I did them & they held for the two weeks advertised & some longer! Rich.

I used a metal conditioner on areas where it was previously exposed to water/condensation regularly.
i.e: lower doors, under hood.

Dilute 4 to 1 wipe on, let sit for 15 minutes then wash off with warm water. It'll leave a white chauky look. a light sanding takes off the heavy amounts. Then primer to metal sealer. Alot of body blasting places offer to seal the car after it's blasted.

After sand blasting I sealed it with this:

No etching primer is required with this.

Great info, thanks!

Kind of on the same subject.
A buddy of mine is rebuilding a TR-6.  It's completly disassembled.
He's taking it to a shop that will bead blast it and put a coat of primer on it for $1K.
Afterwards comes all the body work, a lot of metal to replace and/or patch.
Primarily, this coat of primer is just to prevent surface rust.
Thinking long term, it will be months for hom to finish the ody work.
Regarding the primer, should he ask for a certain kind?

I'd never use that over bare metal, should have bought epoxy, no matter what the label says, same reason I'd never apply Evercoat Fetherfill, Slicksand,e.t.c. over bare : metal, though their labels say it has great adhesion properties on bare metal and aluminum.I've learned the hard way :2cents

any epoxy primer will work

Epoxy.

If you know the final color of your project, pick an epoxy color in the same family.

My original idea was to apply epoxy primer, but the painter says he wants bare metal, and if it's going to be in my shop for a while after sandblasting and doing the metal work, I'd hate to prime it just to have him remove it again.

Most will tell you to seal it as soon as it's done being blasted.  The bodyshop that blasted my Challenger said otherwise...

He said that it would be OK to sit for up to 1 year without being sealed.  That of coarse was in an enclosed garage and the car shouldn't be handled.  It you touched the body, it would start to rust sooner. 

Once my car was blasted, it sat in my parents shop for a year while I found a bodyshop and waited to get it in.  It NEVER started to rust.  Once at the bodyshop it was sanded down by hand again anyway.

If the car is going to be bodyshop shortly after blasting I'd say just leave it bare.

Did you ask your body man if it was a good idea to use the metal conditioner or Picklex prior to him getting it? I don't see that as an obstacle before he gets it.

If you do use it, whichever type or brand, wear rubber gloves. pretty harsh on skin.

Topcat, that's a great idea. I should of thought of that! Don't need any surprises when I bring it to him. I'm leaning strongly towards that picklex20 stuff, but I will clear it wth him first. And thanks for the heads up on the use of gloves. I was wondering how that stuff was applied, and definitely don't need it to eat my hands up!
