Installation guide (peel-and-stick)
-
Prep: Substrate must be clean, dry, smooth, and fully cured; solvent-wipe (isopropyl alcohol 70–90%) and lint-free cloth.
-
Dry fit: Position panels; mark reference lines.
-
Bond: Peel liner gradually, lay from one edge, and roll-press firmly (soft rubber roller).
-
Seams/edges: Maintain tight seams; avoid stretching during placement.
-
Cure: Light use after ~24 h; full bond develops over 72 h (≥15 °C/59 °F ambient; avoid heavy washdowns until cured).
Care & maintenance

Rinse after use; clean with mild boat soap and soft brush.
-
Avoid harsh solvents, bleach, or stiff wire brushes.
-
For scuffs: citrus-based cleaner or isopropyl alcohol spot clean.
-
Cover or ventilate when moored long-term to reduce heat build-up.
