OP,
If you clearbra the entire car, you won't be able to fix small dings. Those dent repair ppl (Dent Wizard, Dr. Dent, etc.) do a pretty good job with small dings. Also, clearbra'ing the entire is total overkill. If you get a little scuff on the door panel, you'll have to redo the entire door panel. Because, once the clearbra film is scratched or scuffed, it's not coming off. Whereas, with regular car paint and clearcoat, a good waxing or detail job can often mask/repair superficial scuff marks, scratches, and swirls.

Of course, it's up to you. If you have the money to burn, go for it. I've clearbra'ed two previous cars. On one car, I did it myself. On the second car, I just paid someone to do it. For my last car, I decided to try not clearbra-ing it since I got tired of paying to clearbra the car and selling it a few yrs later. It turned out that it really wasn't needed. My previous car was also black and the paint chips were minimal on the front bumper.
