I'm borrowing my daughters 1990 Corolla sedan while my 97 Camry is in the shop. I want to try and touch up some of the corrosion for her whiloe I have the car. All the usual places, the corners of the doors are the worst. If I open the door I can see the inner and outer sheet metal coming apart. Not totaly loose, still fairly rigid but not for long at the rate its rusting. Also small areas rusting through at the corners of the wheel wells.
Car has 130,000 miles and is going strong. If I can at least slow down the rust the car should last her through collage????
I've seen some jelly like rust nutralizers/removers?? or should I grind it off? (wont be much left) then fill with bondo?
Any advice would be helpfull.
TIA
Steve
