Rug Installation question

The solder gun sounds like a great Idea. I'll have to pick up an old gun at a flea market or yard sale. If I was to melt the carpet to my sons new gun he would probably brand me with it. LOL. His size my age I am not delivering the spankings anymore. When he gets mad I am off to the safe space in the house to stand behind his mom. She'll kick his ***.
