Yaaaaaa! There she is! The cartridge with the window adhesive. Or silicone. Or Sikaflex or whatever. At the bottom, at the back of the shelf next to the window putty and rat poison. Saturday saved!
That’s what you thought. On closer examination, it turns out that the stuff was not only manufactured in 1943 by the Hermann Göring-Werke with a two-digit zip code. Rather, the content is fixed. Or hard. Or firm and tough. Absolutely useless in any case. Saturday my ass.
The fate of the spoiled, oxidized contents also befalls cartridges if the zip codes have five digits and the brand new thing was only put on the rat poison shelf last week. The remedy is so simple: turn a wood screw into the grommet. And in such a way that the thread bites properly and fully into the plastic. This means that the Spax screw provides a really airtight seal and keeps the adhesive, sealant and paste in good condition for months and years.
