I heat mine in a toaster oven and I use the heat gun just for a second to replace the lost heat from opening the toaster oven door repeatedly. Because I do it that way my heat gun is on the highest temperature setting with the blower on low. Below is a picture of a stand I made for my heat gun. It just prevents any lead or paint from falling into the heat gun when in a vertical position. 2 pieces of wood, aluminum flashing, 1/2 inch aluminum flat pieces to hold down the flashing, and some zip ties to hold the gun in place. Quick, easy, and it will prolong the life of your heat gun.
