HotJet Ceramic header and manifold coat review

[jmassengill]

I purchased Hot-Jet Ceramic Header and Manifold Coating from http://www.masterseriescoatings.com/index/high-heat/

Here are my thoughts on this product:
1. Buy more than you think you need by about double.
This product has alot of solids in it and it doesn't coat like paint does. It also must be stirred to ensure all the solids are mixed with the liquid. Once you think you have it stirred or shaken, stir or shake it MORE. My first bottle had most of the solids left in the bottom of the bottle. I had to buy a bigger bottle to get a good coat on a set of ZL600 headers.
2. Make sure the prep of the parts are clean.
Our first spray of this product peeled off the header like it was nothing.
3. The instructions say to buff the finished product with 0000 steel wool.
Do so LIGHTLY. I went through the ceramic coating without even trying

The product needs to be baked for 1 hour at 400 degrees f or it needs to sit for 48 hours before buffing

I had real hope for this product but it seems that it isn't as good as the manufacture thinks it is. It would be wonderful IF it worked like they say it would.

I have no idea what the long term effects might be. I'll keep you posted.

Did you use the coating on chrome?

The headers were sandblasted before application of the coating.

Sandblasting leaves a fine coating on the pipes that nothing will stick to. They must be washed clean before painting and an ecthing compound should be applied before painting/coating with anything.

i used Poor15 heat paint on one of my zl9,s and had great results with thier etching compound. The paint has been on since 2008 with no sign of peeling. Its not a show quality job as its just been brushed/sponged on but it does stick and can be applied with an air gun for a nicer appearance. As with most heat paint/coatings it will not cure untill its been brought up to temp so care must be taken when handleing the parts untill you get them hot.

etching compound....I never thought about that. I didn't spray the headers. The company that did my powder coating applied the Hot-Jet and did the sandblasting. Food for thought. Thanks for the information.

UPDATE:

I was so bummed about my headers I let them sit for a few weeks to see how much rust would appear on them and how much coating would peel off of them. After a 3 week rest, I picked up the headers and no rust and the buffed spots looked good!

I might have spoken too soon about being disappointed in HotJet Ceramic header coating.
Here is a picture of the pipes on the bike.

Once I get the bike back together and they heat up, during a ride, I'll see if the coating changes any.
