Seven days, one goal a day: handling film, cleaning drills, squeegee rhythm, cutting edges, first heat-gun shrinking, one full window, then a review day aimed at your most common flaw. Scrap film is tuition.
What you need: a roll of inexpensive practice film (ask a shop for their budget line, or buy the cheapest real tint film you can find — not craft vinyl, it behaves differently), a spray bottle with slip solution, a basic squeegee, a knife, a heat gun, and one forgiving piece of glass. A spare car window from a junkyard, an old glass door, or a practice panel all work. A whole car is a later problem.
- Day 1 — Touch. Cut pieces. Peel liners. Wet the glass, lay film, lift it, lay it again. Learn how film feels dry versus floating on slip. Ruin pieces on purpose and look at the creases you make — now you know how they're born.
- Day 2 — Cleaning. Clean the glass, install a flat piece, then peel it and count your specks under bright light. Clean again, better. This loop — clean, install, inspect — is the most valuable drill a beginner owns.
- Day 3 — The stroke. Flat pieces all day. Anchor the center, push water out in overlapping strokes, change one thing at a time: pressure, angle, speed. Your goal is a piece with no water left anywhere.
- Day 4 — Edges and cuts. Practice trimming to an edge without scoring the glass and without leaving a light gap. Light knife hand. Fresh blade often — feel how a dull blade starts to drag.
- Day 5 — Meet the heat gun. On a curved piece of glass (a junkyard rear window is perfect), lay film on the outside and shrink in small zones. Burn a piece on purpose, once, so you recognize too much heat forever.
- Day 6 — A whole small window, start to finish. Run the real sequence from Lesson 3 without skipping steps. Time yourself, but don't race. Write down every flaw and its likely cause.
- Day 7 — Review and repeat your worst day. Spread the week's pieces out. Pick the flaw that showed up most and spend the day on that drill alone. Then stop and notice: you already know more than a week ago.
Two rules for the whole week
First: practice pieces are tuition, not failures — budget for them and don't mourn them. Second: a week of solo practice teaches your hands the basics, but it can't watch your hands. That's what a teacher is for, and it's why the next lesson exists. And carry this out of the week with you: every hour you just practiced alone is worth twice as much practiced beside a working installer — the last lesson in this section explains why.
