I’m replacing a couple of double-pane windows which have lost their seal. These panes sit in wood sashes as part of a single hung window assembly. Pane sits between an outer wood spine and a wood mold frame held with nails. There was this dark gray, very tacky gunk on both sides of the window where it met with the frame. Not sure if the term glaze applies here as it was completely covered by the two wood frame perimeters. This gunk stuff, over the years has begun to run during the heat of the summer. Every summer I have deal with the runs of goo by scraping the glass clean with a razer blade. Never had this problem with any other window!!
To clean the rabbet from where the glass pane set, I used a scraper which I continually had to clean and lubricate with a silicone spray.

I’m about to replace with the new pane and and seal up the window.
Couple of questions:
Linseed the wood needed in the rabbet?
Should I set a bed of glaze? Inner, outer, both?

I was talking to an installer and he suggested I not put any glaze but install the window butt up against the outer wood frame, tacking the inner frame against the window to ensure a tight fit. Then put a bead of clear clear silicone on the outside to seal.
Opinions?

Thanks!
