OK, I don’t disagree but you did say it was a waste of money to insult. So not criticizing you but what is a cheaper way to do it than insulting? All I’m saying is it does help. I insulted my metal garage doors & it did help some. I’m open for suggestions to do my garage doors cheaper than insulting. This is the only thing out there they offer for garage doors.
