Is it possible to heatproof (insulate) stainless steel pot handles? I made a mistake of buying a Cuisinart 6 qt stock pot with two major downsides:  opaque lid (can't see inside) and non-insulated, metal handles.  I wasn't thinking about those features much as I was shopping and the latter now pretty much renders the pot unusable for me because I have a gas stove and the handles get so hot that I have to use a rag or pot holders and I'd rather not have to.

My question is: is there some sort of plastic putty (like Sugru) that can be applied over the handles to heatproof it ?  I was thinking maybe electrical tape but I thought that would melt.
There are a variety of heat resistant silicon accessories that will serve your purpose.
Here a couple from Amazon.com*
