Bob, I don=E2=80=99t know anything about the coating, but if the pistons wer=
e used enough to scuff, how are the ring grooves?  I have good looking used p=
istons,  but the ring groove are worn and out of spec.  Joe B

Joe,

Can't say I'm lucky when I scuffed pistons but mine are okay.  I had a
radiator bottom hose pop off and saw the steam, but by the time I realized
I should shut it down I had the damage to just the skirts. Three were
scuffed a very minor amount so I saved the set . They've been sitting in a
box for years and only now, with this product would I consider using them.
