I have metal (presumably aluminum) drip edge along the perimeter of my roof and will be priming and painting the fascia and drip edge tomorrow. The drip edge is currently painted drak brown and the new color is off-white. The house has already been pressure washed.
Do I need to sand the drip edge or rub it with steel wool prior to priming/painting, or will the primer (Sherwin Williams A100) stick well to the existing paint?
Thanks.
