thats right....... well sorta.....

walmart sells a high temp paint for exhaust header/manifolds that i tried out today and damn!!!!!!

that **** looks like ****ing chrome............ and it's rated to 1000* degrees...!!!

i'll get some pics up tomorrow to show everyone how awsome this stuff is!!!!!

by the way, it's called duplicolor high temp paint, cast coat.....

 

yea, you can get that at any pep boys, strauss, autozone, whatever... I work at strauss and i have seen that everyday i go to work... ur the first person to actualy test it... thanks for teh heads up, now i can get some and get 20% off! yea man

 

1000*


Tell that to the 1200* ceramic spray paint that I put on and burned off after a month or so.a

 

the thing that i liked is how it looked like polsihed headers........ yea, i'm sure people have tried it, but i haven't seen a topic about that paint so far............

but like you said mark, the real test is durability!!!! i think it will do good, only time will tell.......

 

i bet it burns off pretty quick. i have 1500* paint now that stuff

 

just give it some time, the rust will come through

 

damn your a good detective, no fuking chit

 

lmao.

 

z28_dave, u really live in Japan... wow..... what do they call american cars in japan?.... and does everyone wana make there american cars in japan, american spec.?..... do they put english words on there windshields? sorry just wanted to know... hehehe

 

I've used several different brands of "high heat" so called ceramic paint on exhaust etc...

Ceramkot ( sp? ) makes a good product as does POR-15, which has a high heat product called POR20. It's less than $20, and it brushes right on and looks really good. I used the POR20 on headers several times, and it held up very well...the ONLY spots it chipped or flaked was where I ended up having to "clearance" the header tubes with a hammer and some pipe

The want you to "bake" it on for an even tougher finish.... I've had success doing this with a gas grill...


The big thing is the prep work. The POR20 needs to applied to CLEAN ( like sandblasted ) metal. I've had better luck with the other spray can stuff when using a high temp primer underneath. BOTH products do MUCH MUCH better when you give it 4 or 5 THIN coats with plenty of drying or "bake" time in between.

It's all in the prep work. Friend of mine installed a catback exhast on his truck a few YEARS ago...while it was sitting there out of the truck, I scuffed it down with steel wool and sprayed with the high temp alum paint... I put about 5 THIN coats on it, letting each coat dry before I applied the next.

That exhaust system is still GORGEOUS!!! And this is a daily driver truck... the ONLY rust spots are where he had it welded.


HTH

 

I wouldn't exactly call it a "thermal coating". I see those words, I think "ceramic coating".

Heat resistant paint, yes.

Thermal barrier, no.

Ceramic coating provides corrosion protection, heat insulation, and is hard (resistant to scratches). Paint and chrome both fail at the insulation part.

I paid $8 for a can of 1500 degree paint when I ordered my headers. It still looks pretty good after almost a year of driving, especially the headers which I was able to bake in an oven before installing. Thermal barrier - basically nil.

 

I agree....did those paints I used help keep the underhood area cooler? Nope...

As for ceramic coating, such as Jet Hot, it does a great job of keeping the headers, and this the underhood area cooler, but it's not as durable as most people think ( who haven't used it ).

The biggest thing with ceramic coating is making sure not to scratch or mess with it when installing the headers, which can be a pain sometimes.. especially headers that need "clearancing" to fit on the engine correctly.

For the money, I'll go with sandblasting the headers, priming them, painting them with POR20 or something like it, then using headers wrap and the silicone spray to coat the wrap ( keeps the moisture etc from soaking into the wrap )......About $80 vs $200.

I've never had a problem with headers rusting out underneath the header wrap, of course I've always used the spray and a good high temp paint and primer beneath the wrap.....


Just my highly inflated 2 cents
