    Jet hot coatings vs powder coatings

     



    Well here is the main question.When I thought of Jet Hot coatings I almost always thought of exhaust components and maybe I was wrong in that assumption.

    When I thought of powder coatings I always thought of everything else and again maybe I was wrong about that as well.

    So here is the reason behind this question.I was thinking that I was going in the build up of my sub frame of my Astro van,that I was going to powder coat it the same color as the van.That would happen of course after I was done welding all the mods to it.I stated that on the Astro web site that I have been apart of for many,many yrs and the guys there almost all said that because of the hardness of powder coating it would chip easily,than rust,and was very hard to repair.Really not a great endorsement for power coating for a van with a intended use of a over the road tow van.

    The Jet Hot coatings I read here is very durable and is repairable.Hummm??.

    I have eliminated just painting the sub frame because of the road rash that I think might tear it up and return it back to the rusty pc I have now to clean up.

    So what do you guys think I could use for durability on this sub frame that would out last my ownership of the van and I could get in the same color as the pic'ed link of the vendor trailer below??.

    And how does Jet Hot Coatings compare to power coatings??.

    As a side note-I was always told the Jet Hot Coatings/header wraps trapped moisture and promoted rust internally.Again that very well might be a misconception that was passed onto me.

    Thank You for your advise.
    Good Bye

    I think somebody's been blowin' smoke up your butt. You are correct that JetHot is a header coating. If the piece that is being coated is prepared properly there will be no moisture under the coating. There are two or three exhaust coaters that I would trust to do it right: HPC, JetHot and Cap's in Fresno, Ca. Powdercoating is very durable and it would have to be hit a ton to chip it. I recently bottomed out my frame on a speed bump and it was roughed up a bit but the scratches did not go through to the metal. That's all you can ask. None of these coatings are bulletproof, but then, what is?

    Hans,
    The rust factor that I'm speck of isn't from under the coating,but more because it insulates the pipe so well that condensation builds inside the pipe and it rust from inside the pipe out.But again that is a statement in form of a question??.

    We have used that process on race headers,but what I am asking was never a issue as I might be on a daily driver.

    Jet-hot coating and coatings like them are a ceramic based coating. They are very durable and in some cases, help with heat.
    Powdercoating is more a dress up item. It looks like a painted surface but is much more durable and can be wiped clean without removing it like paint. The part does have to be heated to 360 degF for the powder to adhere and melt. Anything metal can be powdercoated.

    As for your rust discussion, it's true the wraps trap moisture and promote corrosion. The ceramic coatings are a good barrier to corrosion on properly prepared substrate. Common practice with headers (or complete eshaust systems for that matter) is to coat both the inside and outside for protection (also additional heat barrier).

    Your range of colors with ceramic are fairly limited, though at SEMA last year one vendor had many more colors available than you usually see, so that's a changing market. Powder coatings have expanded the color selection significantly in the past decade. .

    While there's no reason you couldn't have a front clip ceramic coated (though size might be a problem for most coaters equipment), I think you'd find powder coating more economical as well as easier to find a qualified applicator.

    Luck occurs when preparation and opportunity converge.
