Kind of painting aluminum?
This is posted on the Old House forum too, I didn't know which forum would be best...it is an old house:
So, I have a problem. On my front porch is a railing, and 5 posts holding the roof up. The posts are wood, with the exterior wrapped with some sort of thin aluminium veneer. It is not smooth, but ridged, much like vinyl siding is ridged.
I need to paint the posts. The problem is that I have to paint the railing bright white to match the second floor railing and the trim of the house. But the posts are off-white. It looks silly having these stupid posts be off-white and everything else is white. I could paint the railing off-white, but then it wouldn't match the balcony railing or the trim on the house.
What do I do? How do I paint an aluminum surface that 1. isn't flat 2. already has some sort of epoxy covering/paint on it? I see all kinds of guides on how to paint bare aluminium, but that's it.
Would a regular primer work? I'm confused.
I can't take the wrapping off the posts because then I'd have to take the railings off.
