Does epoxy primer (specifically 29107) need overcoating?

I want to paint a steel door frame. I dont care what colour it is.

Does lechler 29107 specifically need overcoating?


The job is a door frame - its going to get chipped up whatever i do. Slapping some more primer over it when it gets chipped will be easier than priming and top coating every time. But is epoxy uv stable etc.etc?

The choice is yours. The wisdom says that UV exposure may make the surface chalky, but it doesn't degrade. Personally, I would overcoat it. I suspect that you will have no trouble with chipping as you need severe abrasion to remove it.

The rustbuster epoxy 121 i have used in the passed left without top coat has gone chalky.

The black epoxy paint on the underside of my car, which spends most of its time in a dark garage, went chalky.
