I'm tearing my Ford 860 down for a complete rebuild starting with the rear end. My preference would be to sandblast the major parts and prime them. Then when the tractor is reassembled I'll put on a second coat of primer to touch up bolts and scratches, and final paint. I'm curious what others do, what products they use, how long can I go between sandblasting to primer? I've heard that there are product to treat bare metal and go longer without primer. Is that an option to delay primer and paint until the tractor is reassembled since it is in a heated garage. I haven't done any paint work (other than rattle can), so I'm looking for ideas and suggestions.
