I have several steamers I keep with me on the truck, one for backup. I also have 2 heat guns and a little travel hair dryer for backup. depending on the amout of ice, sometimes I start out with heat gun but RAH is right, can melt liner if not careful. Steamer works great, and often times I use either 2 steamers or a steamer and heat gun in each hand, gets the job done fast. Time is money.
