Hi Geoff,
I posted about this a long while back, and purchased a spare pair of steps off eBay for £70 in not too bad condition. Last Summer, I built a “wet-blasting kit” for my new Nilfisk jetwash machine, with the intent of blasting down to bare aluminium, acid-etch priming, and applying an epoxy paint product called “Tank” which is a very tough pickup truck bed paint.
Sad to say, other domestic jobs took precedent over both fine dry windless weekends we had up here in the NE of England last year, and it didn’t happen, but I’m hoping for better luck this Summer!
The original paint shows very poor prep of the metal, there seems to be no primer whatsoever, and as soon as the first scratch happens (usually stones underneath) the slow rot begins….
I’m thinking acid etch, then a zinc-based sacrificial primer, then the epoxy, but it’s a very tough environment where the steps are located
I think if you stick something on, there will be joins you can’t seal, and water & salt will be trapped underneath the covering material, accelerating corrosion. “If it ain’t broke, don’t fix it” -where’s the fun in that?
