Yes the ceramic coating is only for the top (crown) of the piston... after its applied you can take a torch and heat the top of the piston and the underside stays cool... amazing stuff. I thought it would help keep the air/fuel mixture in the crankcase cooler... I know it really lowers oil temp in our racing motors.

stefan,
Do you find this economical?
I would have thought the cost of chroming and grinding would exceed the cost of two or three new cranks.

Wow, thats very cheap. I would have thought the set-up cost just for the grinding would be much more than that.

Why would you grind them?

I give them to the plating shop after break in and the put 7-10 microns of hard chrome on the pin.

Hmmm . . OK, just 7-10 microns is it.
I was just relating to my own experience in having a 1:1 cars camshaft journals hard chromed. In that case the chrome had to be ground to size since apart from anything else, the chrome isn't deposited evenly and also leaves little mountains and globules etc.

But for only 7-10 microns, maybe the issue doesn't arise.
Also, as I understand it (or don't) hard chroming is different from "normal" chrome plating - something to do with ensuring the bond between the chrome and the substrate for a working part as opposed to a "decorative part. Again, maybe there's not an issue since the depth is minimal.

Myself and a few other use Permatex Red RTV without any problems for more than a year.

The stuff doesn't have to be hard, it has to stay put.

Oh, and btw, you know what the real reson for this stuff in the JP cranks is?

JP bores out the crankshaft towards the fron (clutch) to make it lighter and the putty is used to seal that hole, or it would change gas flow and crankcase volume negatively.
