Read this first: These videos teach technique only. They give no certificate and no dealer status. Sign Depot is already a 3M Authorized Window Film Dealer. If a video and the written 3M spec disagree, the written spec wins.

RC Window Films — full install, start to finish (main video)
The main walkthrough: security film on a sliding glass door, step by step — clean and scrape the glass, measure and cut with an extra inch on each side, wet apply, squeegee from the center out, trim the edges. He finishes by stressing the Dow Corning 995 structural silicone attachment between film and frame (shown in his Part 2). The film brand is not named, so watch it for technique; the 3M spec on this page still governs product and bead size.

RC Window Films Part 2 — the Dow Corning 995 attachment
The attachment step that completes the main video: inspect and clean the film and frame, run a continuous bead of Dow Corning 995 structural silicone in the gap between film and frame in a single motion (painter's tape keeps the line clean), pull the tape, tool the bead flat with a hard card, and let it cure fully — do not touch it while it is wet. He runs about a 1/4 inch bead on this residential door; our spec (3/8 inch bite minimum per side, 1/2 inch for blast work) is the stricter standard and governs Sign Depot jobs.

Two visits, not one. The film goes on wet, so the 995 bead cannot. Visit 1: the film (steps 1 to 5). Then let the edges dry at least 14 days. Visit 2: the attachment (steps 6 to 10). Moisture still showing at the edges? Wait another week and check again.
The Job, Step by Step (from the two videos)
Done. That is the whole job: film on, attachment on, curing.

Tips & Tricks
- Keep everything wet. If the film starts to grab, more solution. Never wrestle dry film.
- Dust is the enemy. Clean the frame and the area around the window, not just the glass.
- Start small. Smallest pane first on a multi-window job. Your rhythm is set by window two.
