Problem: 6 months ago, I measured my windows so that I could order insert style windows from a building supply company. I did not know at the time that you are supposed to subtract a half an inch to three quarter of an inch from what you measure, in order to provide for space for insulation. The windows arrived and now my only option seems to be to sand my sills down so that they fit top to bottom. I got one installed by doing this. The left to right width seems to fit okay with about an one eighth to one sixteenth of space between the window and the frame wood. The top is incredibly tight. I can't get the straw to the loctight in there.
I have an explicit question and then I will also ask for ideas more generally. How do I get the loctite into such a narrow space? THe straw doesn't fit unless i flatten it a bit and then it's difficult to keep the straw at the right depth into the crevice.
Quite obviously, I am a newb and did the wrong thing. I would really appreciate any ideas or advice given the circumstances.
