Wow! Looks really cool so far. Cant wait to see it come along.
I think I want my next large tank to be rimless. Very clean looking set up.
Regarding prints/smudges on the stainless. I'd recommend trying Weiman Stainless cleaner/polish. Aerosol can NOT the pre-moistened wipes. I updated all my appliances to stainless last year, so I researched it fairly well. Aerosol Weiman was Consumer Reports top pick. Best applied with 2 clean micro fiber clothes. 1 to apply, and one to buff after its set up. And of course always go with the grain of the stainless.
disclaimer: I have no affiliation with stated product. Its easy to find and has worked for me thus far.
