piston coatings , do it at home ???

JohnRR,

We use the coatings all the time in our shop.
Check out Techline Coatings.
They are very simple to use, and they do work!
We spray all our parts at the shop, and then I bring them home to bake them in the oven. The thermal barrier coatings, and anti-friction coatings DO NOT smell when you are baking them, so you don't have to worry about the wife complaining too much. We do the spraying at work, because that is where all the smell is, and we have a small spray booth there.
Try it, you won't be disappointed!

Which coatings are best for piston tops, combustion chambers, valves, etc.?

Is spraying the pistons really worth the money?

I too would really like to know what other people think about coating the pistons...

Not trying to hijack this thread but my pistons are out of the car and I can either a) do nothing, b) do the home coating or c) send them off to have them proffesionally coated..

What do you all think..

Coat em with oil and shove em in

It's like having too much ignition(or blocking the heat crossover) ..It will help you if you use it, but it's not necessarily a must have. They do reduce wear, extend life, and help keep the heat where it belongs, but they also cost a little for each application. Will you feel a boost? not like a cam swap, but you may notice less tendency to detonate.

For the piston tops, and combustion chambers we use a product from Tech Line Coatings called CBC1.
CBC1 POWERKOTE (Cermet Coating Thermal barrier)
Part #3oz. 2213

Retail packaged version of CBC2/CBX
Designed for Performance engines.
Thermal barrier coating
Reduce part temperature.Keeps heat in combustion chamber longer through the power stroke
Increase torque and H.P. Increase combustion chamber efficiency
Reduce fuel consumption
Water based no hazardous fumes, non flammable
Requires baking. Cures at 300f for 1 hour. Must be oven cured

You do have to sandblast the piston tops, but this is very easy to do. Just mask off the skirts of the pistons, and sand blast the tops w/ new sand, w/ low pressure around 35lbs. Any machine shop should be able to do this for you relatively cheap.

For the skirts, we a product called DFL-1, also from Tech Line Coatings. This is basically the same stuff that Federal Mogul, and other piston manufacturers are now using on their new pistons.
DFL-1 POWERKOTE (Dry Film Lubricant)

Part #3 oz. 2107

All coatings should be applied w/ either a small detail spray gun, or a hobby style airbrush.

Or, just send them to Automotive Machine here in MI and they'll do it for you using TechLine coatings. Check below in my signature line. There is also a price list on their webpage.

Thanks for the info CDPKen. I'll look into the product for my piston tops. I'm not sure about baking my new cylinder heads though.
