I recently came across some spray on window tint when looking into creative ways to tint a compound curve window as seen in many new vehicles. Tinting a compound curve is difficult even for experienced installers, and usually involves overlapping multiple pieces or heat shrinking the film to the window. There might be a better way!
The spray on tint is a unique alternative, if used correctly. This can be applied to the inside or the outside of the windows. Applying to the inside will make the tint look better from the outside, but much care must be taken to prevent overspray.
If you intent to install the spray tint to the inside, first tape off and cover everything near the windows. Now clean the windows with a good glass cleaner and a lint free cloth. I suggest using an airbrush gun to apply the spray. This will allow you to adjust the amount of tint coming through the nozzle. If you spray with less tint and more air, then you will be able to get a more even coating. If you don’t have that luxury, then use the pray cans. Warm the spray cans in warm to hot water to really liquefy the tint. Once the can is hot, shake it up very well for 30 seconds or so. Hold the can about 12 inches from the windows and spray a VERY light even first coat. Allow to dry. Apply a second and third coat if needed to obtain the desired shades, but take the state laws into consideration.
If you plan on applying it to the outside, follow the same procedure as before, taking special car not to get any tint on the painted surfaces. Clean the glass completely and spray as described above. These techniques can also be used to “smoke” or tint headlights, tail lights, corner lenses, and even chrome finishes. The result is really remarkable is time is taken to properly protect from overspray and to apply even coats.
Good Luck, and stay TUNED!
