Thats a good question. It depends on what you are doing. I takes really about 6 months to become good in my opinion in you are doing hail. The reason for that is you are pushing dents from Sun-up to Sun-down non stop. You get much more experiance in a shorter amount of time. If you are just doing door dings probably about 2 years. You aren't pushing as many dents when you just do door dings. However the flip side of it is, if you are doing door dings you are probably working on bigger dents then a hail guy so you get great experiance. I can fly through a bunch of small dents, I am still working on the really big stuff.

I will say this, its a great business with awsome profit potential. If you can get into it and can dedicate practice time, then by all means do it.
