Epoxy over burnished/wire brushed metal?

[kmatch]

I've got tons of trim pieces that have been wire wheeled to remove the paint. The wire wheel leaves a semi-polished look rather than the desired 80 grit scratch. There's tons of places a DA won't go here so before I break a sweat with a fistful of 80 grit, is it really necessary to do this behind a coarse wire wheel?

Wire wheels polish metal, so adhesion will never be as good as with a sanding scratch, imo. You may want to consider a hand held media blaster for inaccessible areas, it doesn't take much to create an anchor pattern.

I have always felt that a wire wheel seems to "smear" the final little bit of the paint, instead of actually removing it. Definately would need to sand or blast the parts.

I have used epoxy on wire wheeled metal for tractor restorations. Some mechanical parts cannot be blasted. Epoxy sticks better than anything else I have used.

For your trim pieces you could get a harborfreight spot blaster for 20 bucks and get your hard to get areas. I would quickly move the blaster over everything to create a blast profile while you are at it. A bad blasting job is better than the best wire wheeling job.

Use fine sand.
