Polishing Foam

[GCooper]

What ever happened to that company that can port and polish with this grey foam stuff?

 

[Dragmeistr]

Are you talking about the paste that they used to use to do TPI runners etc?

 

[Rich Rohrich]

The company is called ExtrudeHone.

 

[Shawn Mc]

You can still get extrude honing done. The company is in the city of Southgate in southern Ca.

One precaution with Extrude-Honing, the cylinder bore on plated cylinders is vulnerable to chipping at the port edges and the bore would definetly need to be diamond honed afterwards, because the abrasive polymer material contains diamond particles.
