Rubberized undercoating

You need to apply a COAL TAR PAINT -- used on shipped -- or a 2 PART EPOXY -- check out the paints used for ships espically the ones used on the bow which breaks though the water. Problem being the metal will be to be very clean or sandblasted with 2 coats of a very good primer applied. Personally I like the primers of water based zinc and then alochol based zinc in the order with a epoxy primer applied with 2 coats of epoxy finish coat of about 4 mils thickness.

A coating of polyurethane should work, as polyurethane is chemically inert, hard-wearing and has (shore) hardness in the 90s. Its composition would be optimised to suit your particular needs. One possible supplier featured in a previous Globalspec article was Rhino Coatings.

We already use Rhino coating on the engine oil pans. It won't work nor will paint/epoxy to cover everything else under the truck, plow frame, steel lines, air tanks, fuel tanks brake shields etc. With the rubber coating you can still remove/repair parts/pieces with relative ease(wire wheel to clean off undercoat)

Thanks

Can you have the trucks painted in a nearby State that still allows painting with Lawson p/n 89154 ?

sorry that's not a realistic option. We don't really paint but spray over anthing underneath after repairs are made.This is very frequent. Our plows take a beating with all the Buffalo snow.

POR-15 is a good product. But there is still surface prep. One way also is to oil spray the underside with siliconeor WD40. This would need to be done often maybe whenever the truck came in for PM.

Funny, how something I've not thought about for awhile has suddenly become my most-recommended idea several times in the span of a few weeks.

Try this stuff, you'll be amazed.

It's not "rubberized" like Rino liners, it does not "cure" like epoxies, but it keeps re-sealing itself and lasts longer than you can believe, while leaving every nut and bolt still accessible and servicable.

After seeing a TV set at a marine trade show working UNDER WATER in a small acrylic tank, I ordered samples sent to our factory. We marine-ized radios, used it as the standard protection for all battery terminals on all boats and cruisers, and eventually the guys in loading/shipping figured out that they could spray it on the semi-trucks for winter road/salt protection - all over any chains, locks, fittings, the entire truck body, etc... and it's not only safe for electrical equipment, it was specifically designed to protect them - you can cover everything but the exhaust (which will likely cook it off).

The company has a website here: corrosionx.com - I'd try the "Heavy-Duty" one, though I don't know where you'd buy it retail in your area. Probably do a Google search or call the company to find out.

I know they set up contracted applicators at airports now to treat aircraft, and have a contract to completely coat all kinds of military vehicles before they get sent across the ocean...

If it'll protect an Apache in the desert, it'll probably be worth checking out for your trucks just to see.

If you have heavy abrasion worries, it may be even better than a product that hardens, since you can just spray a bit more onto anything that gets exposed, and everything else will still be perfectly protected.

I'd give it a shot.

Thanks

what about car wekk undercoating?

I would like to know more about your project, but I am the east coast distributor for Rust Bullet. With excellent chemical and abrasion/impact resistance, it may be the answer that you are looking for. I can be reached at 631.467.6968 or my website is www.socleanblastingservices.com
