Took the paint off of the part, I only needed a light sanding to get the black stuff that it left behind, all of the rust was gone and now the part is ready for paint. Going to go get a can of primer this morning and start hitting it. Need to move the whole setup to the shop now that I see how it works and I can lock the doors to keep the kids out, I also need to get a fire going in the shop today, this weather is nuts. Supposed to be in the 80's next week, wish it would decide what it wants to do. Anyhow now that I see how well it works I am going to do the cylinder and the head in it to get the rust off so I can hit it with high temp black paint.
