Thanks.

+1 stay away from glass beading . Walnut shells would be the only other "blasting material" I would consider. Baking soda is the best.

It'd be best to tape up the ring lands and pin bores.....just blast the skirts and top.

Thanks Lem that's what I'll do. If there is a little mark left. It will just hold more oil! Laughing

The sides of the ring lands are not as critical as the bottom of the ring groove ( where the compression sealing is done). The lands can be rubbed on with scotchbrite and not harm them. Wash thoroughly afterwards.

Ive found that a5o/50mix of acetone and transfluid makes the best penetrant bar none. Ive done wonders with it.
