One thing to be aware of, when sandblasting, is the fact that the sand hitting the metal generates heat. Frequently, sandblasting has caused the metal to harden, in the course of the sandblasting.

I understand your desire to clean up the rust, and there is no doubt that sandblasting is one way to do it. There are other medias out there, to clean and de-rust with. Ground walnut hulls and bicarbonate of soda are but two of them. Whichever media you use, be sure that you protect the bare metal from moisture. Also, you gotta consider that some of the media is gonna be trapped in the cracks and crevices and may show up in your paint job, if you don't get it all out.

It's a delimna, ain't it?
