I bought a few used planes on eBay a few month ago and the block plane restore was the first one to tackle. All these plane bodys and irons was very rusted and pitted when I received them. I posted an article Hand Plane Restoration on this.
Stuff I used for the restoration:
Wire brush wheel for grinder
Black Spry Paint – Rust-oleum
I blew all the loose peaches and rust dust of with some compressed air. Then I proceeded to the wire brush wheel to clean of the iron and plane body. I used the little hand wire brush to get into the spots were the week couldn’t get to.
Once all this was finish i started flattening the blade on both sides. The body took a little more effort to flatten. I used some sand paper and some tempered glass to create a dead flat surface to flatten the sole of the plane.
The body got a good was and sprayed with 3 coats of paint. I dried the surface with a heat gun to make sure no moisture is trapped under the paint. I used Rust-oleum because it seems to be the best paint to protect metal surfaces from rust.

The sharpening of the blade was very easy after I got the iron flat. I am very happy with the end result and started on the no. 7 Stanley.
