Ceramic Coating Questions

[CajunKenny]

I'm considering having this ceramic coated. I called a company and they told me that it would be rated for 2k*F. They also told me that they ceramic coat the entire item. Inside and out and even the mating surfaces.

My questions are:

1. Should something like this be ceramic coated on the inside...would it increase flow?

2. Should the mating surfaces (downpipe side, turbo side, and O2 Sensor side and studs) and threads be ceramic coated?

This would be my first experience with ceramic coating so any info would be great!

Thanks,
-Kenny

I would not, but it wouldn't matter - it's all downstream from the turbo

I would glass bead the entire thing, and ceramic coat the outside.

I actually do high temperature ceramic powdercoating, so keep that in mind

What's the temperature rating of your process and how much to do the elbow?

Also, how thick would your coating be?

Give me a call if you like. 509-528-3951.

why not the oustide?

Always done IN/OUT here then I get a coat of black heat dispersant applied over the outside for the stealth look and to help radiate any external heay away from the part.

Great results with Techline products.

I recall reading Jdub saying that ceramic coating the outside of a tubular manifold, but not the inside, could lead to cracking? I just picked up a used ETS manifold that was coated with black, but I can't tell if the inside is or not. There is just a lot of ehxaust soot and what appears to be some tiny specs of rust...? Should I just header wrap this thing and call it a day?

What about the mating surfaces, threads, studs, etc...? Does all that get coated also?

My main concern would be with the mating surfaces...

Yep mine get a total coating, I put bolts in any threaded holes and mask off any areas I don't want coated.

 

[CajunKenny]

So would you recommend getting the mating surfaces coated too...or not? The gentleman I spoke with told me that there is a better seal with coated surfaces. Does that sound right?

Another one of my concerns was whether or not the coating would be too thick to show the 'Blitz' logo on the side. He assured me the logo would stay quite visible.

IJ how many times do you need to bake ceramic coats? Ima hafta PM you about this since i'd like to learn and eventually do this too.

 

[IJ.]

My guys bake them once to remove any surface oils then once again for each coating type.

 

[jdub]

That is exactly how it's "suppose" to be done...bake, bead blast, solvent wash, apply ceramic, bake. You always want the inside of the pipe and mating flanges coated. Brad quoted me correctly...not coating the inside can cause the metal to crack.

Thanks guys!
