Would like to see the latest in experiences with thermal piston coatings.
Are they worth it?
Have the gotten better?
Do they last?

IMHO with what is available for pistons, you can put that money towards a better set if you are trying to make a cheaper set last. it wont stop a piston that is prone to cracking, stop cracking. at most, it will stave off pitting that can happen from coolant ingestion or other reasons but thats the biggest gain.
I think James is spot on. I personally do not have experience with thermal coatings but have been told by a few reputable engine shops that the coating flaking off is much less of a problem now with today's coatings. I am coating my pistons in my daily driver simply to see how the coating lasts in a 600-800hp application with quite a few miles put on. Until I have cold hard evidence they don't fail and offer a major benefit I wouldn't recommend it to everyone. For the ~$300-500 it costs you could step up from say a OEM piston to a Mahle Motorsport which is MUCH better than the OEM piston for a performance application.
