As more people are hanging onto their automobiles longer (9.4 years is the median age in this country) during this latest economic downturn, not only are there mechanical concerns to consider but you must also keep an eye out for rust. If you live in a part of the country where winters involve snow and ice removal from the roadways, your automobile is more susceptible to rust than someone living in a warm dry climate. Whether you can do something about the rust yourself or if it should be left to the professionals depends a great deal on how much rust and what you are expecting when the job is done. If you have rust areas that are
not through the metal and are 2-4 inches in diameter, you can treat this yourself over a weekend. You will need some sanding tools, paint primer, paint, masking tape and old newspaper. The first step is to remove the rust from the metal. A sanding disc with 100-grit sandpaper should do the trick. Remove the paint and rust slowly, you don't want to grind into the metal. You will want to expand your sanding beyond the rust area so that you get into good solid rust free metal. Once all the rust is removed, begin hand sanding the area with 120-grit sandpaper, then move up to 150 grit paper. Using a tack cloth make sure all the metal to be painted is clean and free of dirt. Use the newspaper and masking tape to cover the area surrounding the prepped area. Use a self-etching primer, applying it in light coats. I generally wait 5-10 minutes between applications of primer. This gives the primer a chance to set up a little and eliminates runs in the paint. Three or four coats of primer should be adequate. After the final application of primer is complete, let it set up overnight. Now you will apply the color matching paint you found at your local parts store. Again, do this in light coats. You will have a better looking job and a longer lasting finish if you are patient and apply five or six light coats rather then one or two heavy coats. After the final coat has been applied, give the paint 10-12 hours to dry and remove the masking tape and paper. Wash the vehicle with mild car soap and after 48 hours apply a coat of wax. This repair process is not suggested if you are looking for a new car finish when completed. It will, however, slow down the progression of rust. If you are dealing with a vehicle where the rust has corroded through the metal, you should seek out a professional repair shop.
