Piston surface....

Re: Piston surface.... (DewMota)
I am no piston guru, but from what I read, the top of the piston should be as smooth as possible. It should be free of burrs, and any sharp edges should be sanded down. Also, I read that polishing the tops of the piston helps. Anything to keep hot spots down (sanding sharp edges) and keep carbon and other risiduals from bonding to the piston top (polishing), helps to prevent detonation.
