I've read about that before but never understood the reasoning of coating it. My tank went raw and did the patina. Never set in foam and set on the recommended rubber pads to prevent another corrosion...
or what its worth I would mop down with bleach after a hose down to get any crevices free from mold growing or even with acetone to quick dry out same. Looks good, any flimsy thin glass take it out.
Just need to add my useless 2 cents.
Hot shower is awesome.
Warm/hot water opens pores. Then use a soap and towel, pull the towel in 1 direction away from your pores in an away motion of your limb.
IE: Shoulder towards your hand.
Cold water closes pores. Thats basic 101 biology 8th grade.
