Raw Aluminum Sign

Postby rbmgf7 » Tue Oct 02, 2018 9:58 pm

Anyone have any experience with raw aluminum finish?

I'm making an outdoor sign and it'll be plasma cut 3003. In the past I've wet sanded to about 800 grit and coated with clear but was wondering how raw sanded aluminum will fair over time in the elements? I know it essentially oxidizes/rusts. The sign has a bit of an industrial/rustic vibe so I'm kinda leaning toward leaving it uncoated.

I think the raw aluminum will water stain and oxidize over time and likley won't produce the rustic vibe your looking for.
