I am starting to redo the Bottom of a 67 Mustang convertable. There does not seem to be much but real fine surface rust. I don’t have access to a rotissery. all the work will be done on the floor. What are your suggestions to (a) remove the rust/ paint overspray (b) seal/ coat the floor panels and subframe areas. From what i read, you guys are very good at this type of work. Thanks for any suggestions that you may have.
