OK guys, Again I need some help here. Geez, this is turning into ....IDK what(being nice)!! OK, there is a leak coming from above my drivers side window. It's right where the gutter ends, and there is a metal strip(vertical) from under the gutter rail to the top edge of my window. Now, this is Not the seam that goes across the roof. This is something totally different. I took off the metal strop and dug in there as far as I could(aprox 3/4")to get all the old stuff out, and then I'm gonna try and reseal it. One question is - Do I use this Dicor sealant to shove in the gap, or should I put that 50 year stuff, then the strip, then the Dicor sealant on top of that?? But the biggest question is....Why in the World would they even do this?? AND right over a window. And why not extend the gutter rail a little more so nothing drips right over my window?? Part of me says to seal the gap, then fiberglass over it and paint. Then I want to work on that gutter rail. Any thoughts would DEF be greatly appreciated. Thanks a bunch for putting up with me.
