I wouldn't paint my shocks, but I think anything metal would be fine to paint other than that. Go over to the 73-79 forum and look up por-15. I'm planning on painting the undercarriage of my truck with that whenever I get the funds and the weather.

The por-15 is made to paint right on top of rusted metal, and it encacpsulates it and keeps it from sreading any farther. They have rattle cans of chassis black coat.

No need to remove anything.
At the same time, apply Fluid Film to fittings, tranny pan, shock mounts, brake line fittings, etc.
- Get truck in the air
- Pressure wash
- Remove heavy scale with wire wheel and putty knife
- Apply POR-15 metal prep (acid etch)
- Pressure wash
- Allow to dry completely (compressed air helps)
- Spread plastic under the truck
- Wear clothing you no longer care about - long sleves and nitrile or vinyl gloves
- Apply POR-15 with a chip brush
- Be prepared to do the entire project, because once open there is limited pot life on the can. Also put plastic between the cap and the can or you will cement the can lid on, and will be sorry.
- Immediately remove POR-15 drips, because once it hardens (including on you) it is there forever.

Awsome thanks, how long did it take for you to do the entire truck? Did you do the underside of the cab etc.?

We did one per day across a weekend. I used the Huckleberry Finn method with a more refined product than apples to get the labor.......
Anything that had paint got POR-15. Everything else got/gets Fluid Film.
