Has anyone used any of their products? I'm thinking of trying some of their stuff. http://www.techlinecoatings.com/
It looks and sounds great, but doesn't all sales literature.

I have used them. Applied the ceramic thermal barrier coating to the tops of pistons for my race motor, and the anti-friction coating to the skirts and piston pins. Easy to work with especially if your wife doesn't mind sharing the oven space with your car parts... :D

We first used their DIY thermal barrier and dry film lubricant about 10-12 years ago... and became believers. At this point I wouldn't rebuild a lawn mower engine without coating the piston top and skirt. But, as Steve pointed out, they need baked in the oven and when my wife got a new oven she refused to share it with the car parts. So now we have our coatings professionally applied.

BTW, I don't think that there is any significant difference in any of the currently available coatings.

I used them on the ProCharged 540 and the new twin turbo I'm building.
