Proper Primer For Storage of Sheet Metal Parts

[Bingster]

What is the right primer to use on bare metal fenders and things to preserve them until you shoot the topcoat?

[Plymouthy Adams]

depends on storage facility and time to shoot......dry storage should not need a sealed substrate...

I primed my bare metal parts with self etching primer for the first coat.

Usually any type of paint should work to prevent rust. A lot depends on how much moisture is in the area that the parts will be stored. I like epoxy primer because you can use body filler over it and it will never absorb moisture.

 You have to be careful with some primers as they can and will absorb moisture from the air.

2k epoxy primer, as mentioned is a good barrier seal against moisture, filler can be applied, but to be honest would rough up the area to apply filers over it and any 2 k urethane primer surfacers will require a sanding once pat the recoat window.

Or you can be an elcheapo like me, use any rusty metal primer, or some type of alkyd(synthetic) enamel primer, sprayed on with it being cut with anything from mineral spirits, to xylene or even acetone, 2- 3 coats for coverage. Heck you can use small rollers and roll it on if you can't spray it.

Again this type of primer once fully cured you can go over it with fillers, 2 k primer/surfacers etc...

I'd like to have fenders ready for top coating.  I assume I'd have to sand whatever primer I use or re-prime it to begin the topcoat process. I'm gonna use enamel with a hardener.  These fenders and such will probably have to sit for a couple of years. I'll wrap them in plastic or something.

I would not wrap them with plastic, they may sweat under the plastic..........andyd

On the 1949...

 

We carefully glass beaded all the fenders, hood, trunk lid, inner fenders and the like.

 

I got the rust preventative "Eastwood Metal Wash".   I did use it a like 4 times the recommended concentration when I mixed it. When I got the parts back I stuck them in the sun to get warm and then I mixed up the stuff and washed all the parts down.

 

I had all the parts in my garage here on the Pacific Side of San Francisco for like six or more months and I did not get any rusting even with the crappy 1920's garage with the salt air blowing around the garage doors.
