Bad paint job

The clear coat is flaking in multiple areas of my paint job. I estimate the paint is roughly 20 years old, as it was this way when I purchased the car.
Question is, can I sand back the bad spots of clear to feather in the edges, scuff the entire car, then spray the whole thing with another coat or two of clear? Or, will this just make the bad spots stand out more? I'm just trying to get by for a few years till I can afford a new paint job. Tks for any input.
