HE Tank Black Insulation??

[lescok]

Hey Guys, I've seen a few members in the past use black insulation on their HE reservoir. Does anyone know where I would purchase this thin black insulation? Thanks in advance

They sell rolls of adhesive black insulation foam at Home Depot next to pipe insulation.
