Well, it isn't rocket surgery but the results were worth the too much work put into it.
After an angle grinder with a cup brush, an electric drill with wire wheel, hand-held wire brush, 60 grit sandpaper and various putty knives...it's done.
She's happy; I'm happy. The heat sucked.
One glitch was...after sanding I realized this was all galvanized (duh). Read my can of Rustoleum metal primer and it said do not use on galvanized metal.
Off to S&W and got a gallon of XIM
Acrylic Bonder and Primer/Sealer and had them tint it gray. I've never used it but will again. It went on beautifully and covered great.
