Lapping Compound alternative

11136 Views 10 Replies 4 Participants Last post by  Ral1121
Has anyone used this for backlapping? All of a sudden my blades are super dull and I don't want to wait for an order from Amazon or other sites. I really need to cut today so I was wondering if this will work? I can buy this locally @ Napa autoparts for about 6.29.

Valve lapping compound is normally 400-1200 grit and is too fine for proper reel lapping.

You need something between 80-180 grit to lap a reel mower.
