powder coat doesn't flake if applied properly, and some coats are tested for and guaranteed to withstand a 180 degree bend without disturbance. the PDF manual explicitly warns to bend only once. i expect repeating or reversing would cause striations/stretch marks at the seam, which would be actual openings in the metal exposing the raw aluminum underneath, not an adhesion failure of the powder coat.
