I recently acquired a C3 which had gotten water halfway up the console. The water stayed that high for a few hours, and then subsided. I am planning on doing a full restoration on this car, but will not be able to begin until this summer or later. I would like to put the car in a position to prevent further deterioration until i can really get in there and rectify the problems. From looking at the frame, the back end of the car has some rust on it, and the front appears to have minor surface rust. Other than that it appears to be in good condition. So far I have drained the engine oil and transmission fluid, removed the carpet, and made sure everything was dry. I have also removed the spark plugs and sprayed some WD-40 in the holes to hopefully displace any moisture contained in the cylinders.
I would like to know what other things I should do in order to prevent further deterioration. Especially with regards to rust on the frame. Is it possible for water to get inside the frame in any spots to where the water can sit in there and rust out the frame from the inside? Any information would be greatly appreciated, and give me an excuse to spend some time with the vette. Thanks in advance.
