Pistons/reconditioning

I wasn't really worried that they would affect anything performance-wise, more like I wanted to clean them up as best I could and wondered about an anti-wear coating. I've noticed most new pistons are coming coated these days. Perhaps there's a product out there that someone's used that thay know will work with no adverse results?
I know the bullet coating I spoke of could stand up to the heat and pressure, after all, we're talking about bullets. And molybdenum is used in many high-pressure/high heat applications. I just don't want to do something that might affect ring/cylinder break-in. So, unless anyone has any proof of something that works, I'll probably leave my experimentation for a Briggs and Stratton.
