insulating the toilet tank

I recall seeing one where the guy had taken some of the political yardsigns, which are made with a corrugated plastic. He cut the sections so that it was a force fit on the sides and bottom, with the sides holding the bottom one in place. He said that after he had a good fit, that he had plugged the exposed openings, but he couldn't remember what he used, and thought it might have been silicon. Said that even if water got in, it would still keep colder water from being able to have much effect on the tank surface. He seemed to be pleased with the result, because he was counting on doing it again if he got another commode and had to replace the tank at the same time.
