Immediately after installation there may be a small amount of setting solution under the film. This is normal and will dissipate in a short time (up to a week depending on climate conditions). Do not press on the area with the solution. The look is very similar to the temporary blemishes found with window film application. It looks like streaking or watery bubbles. This is part of the curing process and these visual annoyances will clear up.
Minor variations in the material itself will also clear up after time and exposure to the elements. Some cosmetic imperfections, often referred as “disturbed adhesive” are unavoidable and can make themselves evident as a result of the installation technique necessary to apply the film.
