Well call me stupid but I have never sealed a hinge gap. I did some searches and all I could find was what to use to seal the hinge gap. Tape, monokote, etc.. Now all I need is a good technique. I am sure it is simple and I'm sorry if this question has been asked a million times I just couldn't find the "HOW" when I did my search. Plenty of "WHAT" but no "HOW" any help is always appreciated
