With nothing stored under the plane in the new hangar I could install the steps. We had them chromed a few years ago. The backing plates were rusty so I sanded them then ground off the sharp edges - then spray painted them with "rust-rid" oxide paint. It dried in 30 mins in the heat.
We then re-drilled all the holes to get clearance back and fillted the steps.
