Found an incredibly clean bed for my truck. The underside still has the original primer and paint on it clean as can be. I'd like to put a protective rust preventive coating on it (and have it be black (it's red) but many of the products such as POR, do not advise putting it on painted surfaces, even if they're sanded rough. Been sifting the web on this. Anyone used a protective coating in this sort of application? I'm starting to lean toward a HD rust-preventive paint like for farm equipment...thanks.

I have a product that is a commercial cosmoline. It's called "Tectyl".
It's also the same type of cosmoline used on the lower control arms.
Kind of a see thru brown. Should be available in gallons?

What about Truck Bed Liner. If applied over a clean surface, it seems to hold up well, even up here, in the "Arm Pit" of The East...
Ever heard of WoolWax
Some guy in Mossouri has a 5Gal container for sail on E-Bay for $100.00/Free shipping.
That's a screaming deal!

I tried something different on my dad's truck.. Fluid Film. It looks and smells a lot like cooking grease and get this.. you thin it with vegetable oil. It's supposedly been around for quite some time and was supposedly used on Naval ships?
Over the years I've tried tar like products, POR15, etc but always felt oil worked the best. This product is much like an oil and wicks into crevices plus stays soft. They offer it in it's natural color which is yellowish or you can get it in black, you can buy it by the gallon and thin it yourself or buy it in a spray can.
Can't say how well it works yet but it looks like it should do the job?

I have my 04 Tundra Crew Cab with 200,000 miles shot with fluid film every year underneath. When I bought the truck used it had already had the frame recall done in 2014. The frame and everything else still looks good for a NE truck that sees lots of salt every winter. Fluid Film is a Lanolin based product and stinks for a few days after application but unlike oil it will not attack rubber parts like oil can.
Thanks much for the information! I've started looking up these products. My application will be brushing the stuff on to avoid the hassles with spraying it, ventilation, etc. My concern is finding a product that will stick over a solid base of primer and paint. I've been scotch-briting the underside for adhesion of what I find can adhere to it...
Thanks, do you know if this product can be applied over primer/paint? Been looking at their website so far nothing caught about this yet. I see it is also available in black that I'd like to have.
Yes, it can be applied over painted surfaces. $100.00 for five gallons is a great deal. this stuff is expensive!
You should be ableto go to their web site and get all of the info you need.

In gallon form Fluid Film is pretty thick and can be brushed on, I spray because it quicker and gets into hard to get to areas.

I will say Fluid Film does work well but it ain't pretty. Dirt gets stuck in it. When I first had it done the guy that did it said "No under carriage wash" " "Best thing to do now is take it on a dusty road."

Do you have one of these Harbor Freight blasters? They actually work pretty decent. I would use that and then epoxy primer. Then your Fluid Film or bedliner.

If the bed has a solid original coating, why would you not just put another layer of coating on it that is permanent? Why use the annual oils and the mess? Especially in WI where (believe it or not) winter is not as constant of a battle. Just a 4 month siege.
I would scuff it, epoxy prime it, then coat with a chassis coating that is hard and durable. Eastwood chassis black comes to mind.
That way in WI you can actually do an undercarriage wash on the few warm days everyone lines up at the carwashes.
Side note: If the bed came from OUTSIDE a rust area (Like the south), every tiny chip will rust like crazy a year or so in WI, so be aware of that.

Yep, this box is really clean and seems unnecessary to remove the original paint/primer it has but to recoat over it with a rust preventative product...been looking at some mentioned and another called 'Rust-Bullet' that can be applied over the primer and paint. It comes in black which is the color I'd like it to be.

Ask people about that. I have used Rust Bullet, POR 15, and Eastwood encapsulator and I personally thought Rust Bullet was the worst to work with and POR 15 coming in a close last place. From my experience, an epoxy primer does a very good job as a base. I have used 3 different kinds and they were all very similiar, so take your pick. I have also found that Eastwood Rust Encapsulator makes a good primer base and comes in black, but does not have UV protection and would need a topcoat if its used anywhere but under the truck. It is kind of expensive, so a different epoxy brand might do fine. Here are some example pics (sorry not a mopar):
The silver shown is Rust Bullet in silver. It had a tendency to not coat smooth and seemed to be a bit too thick. It may have good rust capability but looked bad to me (this is the bottom of a Triumph Spitfire). I stopped at these two areas and switched to Eastwood rust encapsulator because the Rust bullet was pissing me off on how bad it was to work with.
This is after I topcoated with Eastwood Chassis black in satin. This wheelwell has a Eastwood Rust encapsulator primer in red under it (no rust bullet). It flowed much better and applied very nicely. For the record, both sides have prevented rust and look good for under a car, but I found the eastwood side was much better visually.
Also, the Eastwood chassis black makes a very hard surface and I find it repels dirt and rocks really well.
So, there you go, some real pics of what you are considering. hope it helps.

Thanks much for this info and photos. I had read reviews about rust bullet drying fast and being wasted (becoming unusable...great considering the price for the stuff) and as well as a bed liner material I was reviewing. I put a few coats of primer on the floor and trunk of my old ride and installed dynomat in the cab over the primer.
