So 3 weeks ago I bought my 1977 Monte Carlo, it got painted and is currently getting an up to date stereo system installed. Now I am faced with another issue that I had to call on some help for, my inner fender wells are rusted pretty bad. They need some serious work done to them and I need some advice, what are some low cost fixes, what will last for a long time without following the same trend. I live in Rochester and there's a lot of salt the body and the frame aren't rotted out, but little things are starting to get some surface rust on them and some tips on how to keep rust away would be highly appreciated as this Monte Carlo is my daily driver. I hope to hear from someone soon.

 

You will either need to replace the inner fenders or cut out the rust and weld in a metal patch. After the repair is done, spray some aerosol rust proofing behind the area that rotted out if possible. Will at least delay the inevitable. If it rusted there once it will probably rust there again in time. All you can really do is make the process take as long as possible.

 

Weld in patch spray with a rust etching primer and spray with undercoating.
