Why not?I'm talking all gaps. Foam should never be used to close a gap between a tank and a stand.

I don't know who came up with the idea insulation sheet under a tank. Its ridiculous. I had tanks all my life glass and acrylic. I never put that crap under my tanks. Acrylic tanks get a layer of ply-wood under the tank. (As seen on Tanked and Fish Tank Kings) This idea probably came up with the acrylic tanks that are under sized. Thinner acrylic. The ones that bow when you fill them up. If metal stands are made right (square and true) the tank should lay flat with no rocking. Save the insulation for your home to save money on heating and air conditioning. Thats where its supposed to be used. LOL You will be fine. Good Luck
I'll answer your second question, yes you can paint the plywood under that tank rather than the tank itself. Be sure the paint is fully dry and cured though or the tank will stick to the paint.
Another option if you don't want paint is to use vinyl flooring remnant in your preferred color choice. I did this on my racks of tanks and am pleased with it even though I do use substrate in my tanks.
Did you ever confirm whether the tank has plastic trim or is rimless?
