I've mentioned this before, don't know how many of you use two heat guns already, but if you don't, try it. It makes shrinking or heating up an area twice as fast. I've used it for years, and get frustrated when one of them goes out, till I get a new replacement. Seems it takes forever to shrink using only one. Just take two guns and tape the handles together with duct tape. They have metal holders, but they hold the guns too far apart, the heat is not centralized enough to do the job as well. I have a holder and don't use it for that reason.
