Painting metal posts
I have steel posts supporting my carport. They need to be painted.
The paint on them is peeling and some rust has begun. How do I prepare surface? What type of paint is best, oil base or latex?

Scrape or wire brush as much f the loose rust off as possible. Next treat with a rust-conversion coating. Ask the guys in the paint department. It's a creamy product that you brush on. After a couple of hours the surface turns black - the rust has been converted to a non-corroding, paintable surface. Topcoat with a good oilbase like Rustoleum.

While converting or removing all rust is best, a decent sanding or wire brush/wheel followed with a rust inhibitive primer and oil base top coat will do the job. Never use latex on rusty [or prone to rust] metal!!
