I am not sure how many total hours these pistons have. Guaranteed to pass your inspection or money back. I stripped them in an acrylic media cabinet which is very gentle and does not etch or pit the metal.
Your finger nail catches slightly but I would say very usable pistons. The only defects I found was light scuffing on skirts.
I'm buying new cylinder assemblies for the rebuild. It is very light and you can't feel when rub your finger over. These are just under 200 dollars new, the aircraft had a top overhaul 380 hours ago but cam lobe went.
