I replaced my exterior doors with pre-framed steel doors. The old doors had 1 x 1 1/2 wood brick molding. I looked at the products at Home Depot and Lowes and they are 2 x 2 inch brick moldings. Should I cut back the stucco exterior to make room for the 2 in. molding? Or should I ripe the molding into 1 inch strips. That looks like it will go poorly, since I am wanting to use the pvc molding product. Hoping the platic will last longer than wood aginst rain, weather etc.
