roth metal flake question.

I am going to have a flake roof done on my 55 Olds when it is time, hopefully by this summer, and think I am going to go with the Roth flake. I wonder if a novice can do it with their bomber gun? Great color choices.

 

Suspended in clear and shot through an hvlp gun with a 1.8 tip. I drop a couple of 1/2 inch nuts in the cup to help keep it stirred up and empty my cup and rinse the gun between coats.
