The stairs are similar to those in the left photo here:
The four stairs connect a kitchen door to ground level. Foot traffic is
fairly light, mainly one adult.
Over the decades they have been in place they developed some deep rust
pockets. (No part of the stairs or landing has actually rusted through.)
I first powerwashed everything and then scraped with a putty knife.
Finally, I removed most of the remaining rust with several applications
of Naval Jelly.
I'm looking for recommendations for finish primer and topcoat. Rust
Oleum makes oil-based primers and finishes for such use. Any better
products out there?
You didn't say what color you're painting them. These guys have limited
selection but it's generally regarded as the best for metal, particularly if
there's rust on it
already. www.por15.com I have found Rustoleum to work ok but not nearly
as this stuff. Disclaimer: I'm using this on my offroad Jeep so it's
putting up with mud, rocks,
etc... Rustoleum may work just fine for stairs but you probably will have
to recoat every couple of years
whereas with the POR product, it may be more like 5 years.
