I'm considering using some type of thermal barrier coating on the pistons, combustion chambers, and valve faces for my new engine. Has anyone tried this company's product?

They claim that home application is no problem and a whole engine kit is reasonably priced.

Anyone out there try this? Is it too good to be true?

Carl,
I used there engine kit to coat my pistons and combustion chambers, I am also going to use the WSX that is included on my lifter bores. I could not bring myself to "SAND BLAST" my bearings or cam to apply the DFL-1 (Dry Film Lubricant) I only applied it to the sides of the pistons and applied the Thermal barrier coating to the piston tops and combustion chambers.
It is not that hard but does require the ambient temp to be over 70 for the stuff to stay in a liquid state. I tried to use an Air Brush but ended up useing a paint touch up gun.
For the price I would do it again, to have some one else do was going to cost me $30.00 a piston (=$270.00 including shipping). E-mail me if you want more info or have specific questions that I did not answer.

Tony,

Thanks for the info. If it's OK I'll post the questions so we can learn from your experience.

I too am a bit nervous about sandblasting new engine components. My main concern is keeping the heat in the combustion chamber.

Did you have to sandblast the piston skirts, tops, or combustion chambers? If so what grit?

Did the heads need to be resurfaced, due to warping, after heating? Do you have aluminum or cast iron heads?

How did the final result turn out?

I have heard opposing views on this theory. I think i would like the friction reducing theory for the sides of the skirts but i have heard that thermal coating on the piston tops sometimes does not let you build enough heat in the top of the piston for efficient combustion.

Carl,
I was more concerned with the amount of space being used in my reply as I read a note from Dennis that things are getting tight.

1. I taped the ring lands and piston pin bores off very thoroughly and then sand blasted the exposed area's (I have pics available) using a syphon feed sand blaster at 35-40 psi as per TechLines instructions. I put in a set of old valves and taped off the deck surface and did the same for the combustion chambers. I used 100 (not grit like sand paper, but very fine sand available at most hardware stores like Lowes/Home Depot) silica sand.

2. I had a valve job done afterwards but that is because I installed 2.05 intake valves. I have Sportsman II iron heads. They did not surface them because they didn't need to be surfaced.

3. I think they turned out great, I am still in the process of building my motor as I have been recovering/repurchasing parts that where stolen from me. As to whether or not this will make a difference we shall find out.

I am using the Thermal barrier coating because I want to reduce the risk of Detenation will running Nitrous and to help reduce the carbon build up on the pistons/chambers.
