I am renovating my basement and noticed the 2 window frames have a metal bottom frame that have metal flaking off. My idea to resolve the issue is to use a small hand sander to remove the flaking paint and simply use a paint brush to put a new layer of paint. I have a few questions:
1) Why would metal be used?
2) Why is it flaking? I don\’t notice any moisture nor do I see any damage to the sheet rock
3) Can basic interior paint be used (e.g. ceiling / flat paint)?
