I'm getting some peeling on my tubular manifold that I had Jet Hot coated. I wanted to get it re-coated, but didn't know if that was possible. Has anyone had this done?

 

when I used Jet Hot coating I remember them having a guarantee that it will not peel. Call em and see what they say.

 

its not a trivial matter to get a paint to stick to a manifold that is repeatedly thermal cycled from RT to ~1000C. It will spall...sooner or later

 

Yeah, I was wondering if it was bead blasted or sand blasted it could be coated again. No question it's a hostile environment for any coating. Anyone else?

 

do not bead blast, surface compaction will not help adhesion

grit/sand blast, increases surface area and "mechanical anchoring" for the coating.

prep the surface well after the above, de-dust, degrease and dry - helps film to stay on better...

 

if you did not install your tubular manifold for say a couple of weeks and then send it to get coated then the coating will fail. I have had enough fun with the tubular manifolds to never buy one again. Unless it is a full race or Shearer because those are in a different league.

Or you can just get a stock ported/coated manifold that we sell and it will never peel!

 

Jet Hot has a woarranty on their coatings...send it back to them and they should fix it for you

 

It's certainly worth a try. I purchased the tubular manifold from a "former" Evom vendor so I don't have a contact for Jet Hot. Would someone have a contact?


edit: Never mind...before someone told me to search, I did and found a contact.

 

if you didnt buy the coating i do not think the warranty is transfered. but its not that expensive. But if you do recoat it do jet hot 2000.

 

Just because it's pealing doesnt mean the thermal properties from the paint are not still on the material. I was told a while back they would still be on there. After trying a couple different coating companies and doing a lot of research with Full-Race Geoff I came to the conclusion Swain Tech > *
