Almost every reputable dipper out there is going to use an automotive base paint and an automotive protective clear coat on whatever you have dipped... So the finish is whatever he puts on it...
Every dip is going to require 3 things. Prep work is key, a proper base coat of paint, and then a careful dip... The last part determines how durable the finish is and thats all relative to the type of cleat or top coat he seals it with.

So, if you can take your cars finish for an example... Thats pretty close to the same durability
