I am building a skelton structure out of some angle iron, and I'm wondering about a decent method for painting it. It will be indoors and doesn't really *need* a paint job, but I'd like to paint it anyway.
The angle iron has a coating on it from when I purchased it, sort of a grayish color. While I have wire brushed coatings like this off in the past for small jobs, there's too much iron for me to fiddle with the brushing this time; is it generally okay to paint over the stuff that angle iron comes already coated with, and if so, should I use a primer first?
I'm also looking for a recommendation on a "decent but cheap" spray paint; I'm not looking for an automobile finish, but want something a little better than $0.88 Walmart rattlecan; ideally something good that's two or three bucks a can.
Thanks for any suggestions,
