I sprayed some Cerakote last week on a piston crown.  It is considerably more expensive than high temperature exhaust paints like VHT and similar spray cans - and it does require that you own a small "touch up" size spray gun.  It does however go on really easily and the durability is really impressive.  (I have used VHT on headers and it holds up OK until you ride in the rain).  The 4 oz tester is likely plenty to do a couple of Savage headers.....it covers very well and sprays easily - but it is very stinky and requires good ventilation.  (When I sprayed the pistons I did it outdoors - but even bringing them in the garage to cure was too stinky and I moved them back outdoors).  The paint on the headers takes 5 days to fully cure.

Wow  

Does it come in CHROME  ?

Cerakote on a piston? Kinda srslee needs to stay on..
I had no idea that was even a possibility.
What is
The Win?
Why do you want that?
Is it worth it?

I have never used the product, but from some things I have read exposure to fume is very dangerous. Not just exposure to the atomized spray, but the fumes from the spraying and initial cure. I have seen it said that if you can smell it, you have had a potential over exposure. Extra caution may be appropriate around using it.

Money , Money , Money ... but it sure does look Good !  
:................

I've used that rattle can chrome for non heated items it's OK .  

I've got the overheated stainless steel look for now.  

So

If a person was building a drag-race bike and was planning to burn nitreous  oxide ... then ... coating the piston(s) with a heat shield might be a good idea ?
