Our house is a 1974 Ranch style with aluminum storms and screens over wood frames. It still has the original aluminum siding as well. I removed the storms one by one and painted the bulk of the wood under them. Now the old aluminum frames look tacky ... I gave thought to painting the frames to dress them up a bit. I slobbered a bit of paint on a few spots of the aluminum (Final coat after replacing the frames), it seems to be adhering pretty good for now. However, I don't want to take the time to paint all the aluminum if it will fail prematurely.
I took a painting apprenticeship years back and it seems I remember that a surface such as aluminum needs to be "acid etched" for paint to properly adhere.
The paint I am using is McCloskey's House and Trim with primer in the paint ??? Don't have the can in front of me right now but, it's a paint and primer all in one.
Someone in another forum suggested using a Rust-o-leum primer but I don't think that is formulated for aluminum either.
Any suggestions or solutions will be apreciated.
