Hopefully you'll see this & it's not too late. I can't personally recommend a hot glue gun but Allen Hopps (Stiltbeast Studios here on RU-vid & owns Dark Hour haunted house in Texas) has recommended over & over the site glu-stix for hot glue supplies. The gun he uses is the Industrial Hot Melt Glue Gun - 500 Watt - 5/8" Sticks & he highly recommends it. It's waaaaay too expensive for my budget but the site does have lower priced guns. They also have a great variety of glue sticks. Hope this helps.
