Going to give this a try to help finance my current project.
I just polished this proportioning valve for my project to see how well it would come out and was happy with it.
Send your Proportioning valve and $35 and I will get it polished to the shine you see and ship it back to you. Should be able to get it back in a week.
If you want the edges polished as well it would be $50. The $35 is for the sides only and the edges cleaned up. $50 is for a completely polished part.
Let me know if you are interested.
Thanks.
