So, I'm something like a week off finishing my current build. Chassis is complete, electronics done, metalwork 70%. This one will feature some fairly deep etching in a few places. I've been doing test etches for a few days now, I've refined my technique to the point where I can reliably get my etches to about 0.4mm deep with little to no under etching. I'm at the point where I'm ready to etch actual MHS pieces.
The only thing I'm not 100% happy with is the etched area itself, both from a visual and tactile point. Visually, that raw etched alum look is a little unappealing, which tactily, the etched aluminium feels somewhat... odd, to my fingers. Is there any way to clean it up? I know painting over the area is viable, but I was wondering if there was anything like an abrasive slurry or paste that could be scraped around the etched metal to smooth it over a bit.
