frame paint/protectant
I was wondering if there was any consensus on what to put on the frame during a frame off restoration. I've got my entire truck disassembled and the major parts are currently at the sandblasting shop. All the sheet metal will go the body shop for priming. I was considering doing the frame myself. I can find material online about DIY folks brush painting their frame and being happy with the results; however, they don't update those articles 5 years later when trouble appears.
The truck had sprayed undercoating on it a few years after purchase. That step is probably why there's even still a frame to work with
I'm just looking for stories on what worked and what didn't. Leaving it to the paint/body shop is an option too!
Thanks!
John

If you are doing a "correct" restoration, be sure to use a protective covering with the correct sheen. If you're doing a resto mod, use something 'pretty'.
The frames had very little, if any paint protection when new and unless they were subject to salt, many of them remain in very good shape today with very little rust.

Ray,
You make a good point. My frame has a small bit of black still showing in a couple sections. What would the original paint on these frames have been? And what would be the correct way to restore them now?
Was the original more of a gloss black or satin black?
Does anyone have any old pictures that show exposed frame and how they looked?

Thanks for the info. Seems like a strong product indeed. I just want to put something that I can forget for 25 years No ambition to have her this far apart again any time soon!
I feel like the sand blasting adequately replaces the prep step. Their website has so many products though...they suggest with bare metal I can go straight to the top coat or use the rust preventive first. For top coat they have 1 and 2 part versions. It feels a bit like guess work on an important step.

For the frame, I used their Chassis Black product. This is a direct to metal coating that is UV tolerant. So with some wire brush action and a quick degreaser wipe down, the surface was prepped. They do have some good products that readily adhere to metal. In fact, I used the Chassis Black product on the bed of my '49 (interior side walls and original metal floor). After five years of routine sun exposure and abuse while earning it's keep as a working truck, the paint adhesion / color endures. I'm very satisfied with the POR's products.

A buddy is a big POR15 fan but I can't figure out why, he is always repairing spots that have flaked and throwing out paint that has hardened in the can. I have used various products but I am a big fan of KBS Rust Seal. As has been noted, this product will fade when exposed to UV (sunlight) but how often does your chassis ever see sunshine? KBS also comes in many colors and sheens and is less expensive than POR15.

My friend Ray Tasch got me going on a product called "Ospho" to kill any surface rust. It goes on like water and when applied to rusted surfaces causes iron oxide (rust) to chemically change to iron phosphate which is an inert, hard substance that appears black. Once dry, the treated surface can be overcoated with whatever paint system is desired. I used this Ospho and then I brushed on one coat of Rustoleum Primer and then a couple coats of Rustoleum Flat Black. It looks far better than it did when I got the truck. I will report back as to the durability of this treatment and paint combination in say.......15 years.

Eastwood has a bunch of products but as you can see everyone has their favorites. Kirk has a good list but whatever you choose it has to be better than what was originally used . . . which was probably ground up used rubber mixed with acetone. It may even have been different plant to plant.
