Paint - Stains Under Paint Guard Film

PAINT STAINS UNDER PAINT GUARD FILM (PGF)
APPLIED VEHICLE:
All models with PGF applied
SERVICE INFORMATION
In some cases, moisture may have collected underneath the PGF (Paint Guard Film) causing stains to be present. Stains are usually visible immediately
after removing the PGF and can occur on the hood near the washer fluid nozzle. The stains can appear as a darker shade than the body color, and have an
irregular shape and will more likely occur on light colored vehicles (i.e. Platinum, Beige Pearl, etc.).
The phenomenon is caused by water and/or windshield washer fluid being absorbed into the paint when the PGF is applied (paint is porous, like a
sponge). The water trapped in the paint causes the light to reflect in a
different manner between the metallic particles, resulting sometimes in a darker appearance.
The procedure beginning on the following page has been found to be effective for correcting paint stains caused by PGF.
SERVICE PROCEDURE
Heat Gun Method
CAUTION:
This procedure should only be performed by experienced paint technicians familiar with paint temperature limitations. Do not use on painted plastic
parts (e.g. bumper covers, spoilers, etc.).
Using a professional-type heat gun, heat the stain area using the following guidelines:
Gun specification:
1200-1400 Watts
Paint surface temperature range:
approx. 175-190 Deg. F (80-90 Deg. C)
Duration:
Until recovery (maximum of five minutes)
Heat the incident area with the heat gun, keeping a distance of approximately four inches from the tip of the gun to the painted surface. Do not hold the
heat gun in one position. Keep moving the heat gun using a side-to-side motion in order to heat the affected area evenly.
The stain should begin to disappear within 60-90 seconds. If the stain does not disappear after applying heat for five minutes, the stain may be permanent
and the panel may need to be repainted.
NOTE:
Maintain heat gun distance so that the panel surface temperature will not exceed the specified range. The panel temperature can be monitored by
using a temperature indicator device such as a paper thermometer label (self-adhering label). The label should be applied directly to the painted
surface adjacent to the stain area (about two inches).
When using a heat gun, do not apply heat directly to the temperature indicator device as this will immediately increase the temperature label reading and
may not be representative of the temperature of the paint stain area.
Paper label thermometers are available in a variety of types and temperature ranges. One type that performs well for this procedure can be obtained from:
