I am having my box gutters re-lined using galvanized steel. Contractor One
says they do not need to be painted; Contractor Two says they do, using a
Rustoleum-type paint, and that they will need to be repainted every 4 or 5
years as regular maintenance. Do box gutters need regular painting?
Also, does the gauge of the steel make much of a difference? Contractor
One specifies 24-gauge, Contractor Two does not specify the gauge.
FWIW, I will be getting at least one more quote.
