body work tools question

With 2 Young kids (3.5 and 5 year old ) the time and funds are not available at the moment, when I did the body and paint on my last car (68 dart) it was down for 4 years. And that was when it was just the wife and me lol. I had another thought of shooting the car with a matte clear just to protect it until I can do it right.like I said there are lots of bare metal spots on the car now that I have been treating after almost every ride. But it is a very solid California car.
Personally I would strongly advise against doing this. You mentioned that you are looking to fix some dents now and eventually repaint the original color. Why not just paint it the original color now? You have a nice solid base to work over, why muck it up?
