Hi all, I need some advice on permalac and buffing/additional coats.

Backround:

I took a job to refinish a steel chair made by another artist out of railroad components. The steel had been ground with a swirl finish and clear coated with a clear powder coat. The chair was used outside and over the years had started rusting of course. The client contacted me to have it stripped, remove the rust and put the swirl finish back on, and have it clear coated with powder coat.

We have recently tried clear Permalac on some exterior ironwork and it seems to be holding up well. The pieces were not heavily forged, more bent and a clean wire-brushed look was what we were after.
