What this video covers
Sven Yrvind tests whether old adhesive sealant is still usable for installing windows on his small cruiser, the 5.9.▶ 0:06 Some tubes date to 2019 — roughly seven years old — and one is marked expired 2023, but it remains fluid.▶ 1:32 His test criterion is simple: if the sealant has not hardened in the tube, it still works.▶ 1:16 He plans to wait until the next day to confirm the cure.▶ 1:47 Alongside the adhesive test, he identifies two preparatory steps before bonding the glass: grinding the mating surface to create a clean, rough substrate, and fitting small rubber spacers so the glass sits proud rather than bearing directly against the hull.▶ 2:04 The work is staged — surface prep and spacer placement come first, adhesive application follows once the old sealant's viability is confirmed.
