Auto body repair & detailing: Rust spots, rust spots, wheel wells

Question
I have a '93 ford explorer. Underneath my two rear doors, between the inside of the floor and the outside plastic trim on the lower side of the vehicle, there are rust spots about 7-10 inches long. In the middle of the spots on both sides the rust has eaten all the way through and on my wheel wells also (the wheel wells aren't as bad, I want to catch those before they get too bad) I just wondered what techniques or what I process I should use that will effectively patch the holes and prevent the other rust from spreading and getting worse. Thank you very much.

Hello Chris,
 You will have to clean out all the rust with a grinder and/or wire wheel.  We use metal plates, cut to fit, to patch the holes.  We weld them on but you can bolt or rivet them on also.  Then you will have to do the finish work and paint work.
 We would suggest taking your vehicle to a body shop for these repairs.
Thank you,
