"When installing window perf or other vinyl, many glass surfaces have wax or other invisible coatings on them (like RainX) that interfere with adhesion. Place several drops of water on the glass, if the water forms into beads there is a coating that must be removed. If the water does not form into beads there is no coating and you can proceed to clean with isopropyl alcohol."
“Frosted GlassApeel is amazing. The prints are crisp, the colors vibrant (without white ink) and it looks great when viewed from both sides. It handles Latex like a champ and lays flat. Apply it to fluorescent lens covers or interior light boxes and it transforms a room. Best of all, you can remove it in seconds and store it to reuse later.”
