Thinking about paint durability

[D.P.N]

I am in the process of tearing down an old 1010 crawler. I intend to rebuild and use this tractor around my place. I refer to this group often for pointers, ideas and advice, so let me pose this question: from a point of durability, can I expect better better wear from an automotive paint such as PPG Omni line as oppose to an two part epoxy coating such as Sherwin Williams Tile clad? I am currently using the epoxy to paint an old milling machine and have used it on many of my shop machines, it seems really durable. This is my first attempt at using an automotive type finish
and have no experience with the PPG product. What do you guys think?

for a working crawler, the tile clad is a really tough industrial and marine coating. chemical resistant, salt water resistant, all kind of stuff. if you are not looking for a show piece, i think the tile clad is a better choice. altho the automotive paints are durable, they will not hold up to the enviornment the tile clad will.

Sherwin Williams Tile Clad is an epoxy product. Epoxy is tough and has good chemical resistance, but sunlight causes it to deteriorate. That"s why epoxy isn"t used to paint cars. For best results I recomend that you use a urethane enamel. Although epoxy is resistant to more chemicals than urethane, urethane is not damaged by exposure to fuels, oils, brake fluid, alcohol, and most solvents. Urethane is tough and durable, it is used to paint locomotives, aircraft, water towers, dump trucks, and industrial machinery & equipment. Down sides.....even the industrial grades should be applied over primer; if sprayed, proper breathing protection is needed; and like epoxy, good urethane isn"t cheap. I have found the industrial urethanes tend to be somewhat less durable than the more expensive formulations, and they don"t cure as glossy. But on the up side they are cheaper, easier to apply, and go on heavier.

Tile Clad has it’s limits, indoors. Otherwise it degrades within a year with loss of gloss followed by severe chalking.

With FORD RED’s urethane suggestion, Sherwin-Williams‘ “Polane Plus Enamel”, a two component cross linking acrylic urethane topcoat came to mind. It finds use in OEM production applications including heavy equipment and agricultural equipment fabrication.

Apply it over their E61RC22 Catalyzed Epoxy Primer and the end result will be exceptional fade resistance, color retention, corrosion resistance and wearability.

The drawback with Polane will be availability, it is an intermix product and SW ships it to order from “blending stations” to the point of sale. If a commercial branch store handles Tile Clad, they should be able to assist with the Polane product lines.

If you want the best 100% polyurathane on the market ,then try DUPONT IMRON two part epoxy. longest lasting and outstanding gloss. plus resistant to most chemicals. be sure to wear supplied air mask. good luck
