What is the process of repainting aluminum window trim that already has a coat of paint on it?
The house has aluminum trim around the windows and the previous owner painted it a darker color. I'd like to return it back to white. Since its already painted should I just scuff up and put 1-2 coats of paint on top? Or would it be better to do 1 coat of primer, and then 1 coat of paint?
No peeling and it looks adhered everywhere, its just an awful color I want gone.
Wipe with a TSP substitute beforehand? Scuff sand quickly?
What are suitable exterior primers and paint types to use for? Urethane enamel, or an Acrylic latex?
