Question: I have a puncture in my POLYCOTE ECS.  How do I patch this?

Answer:  If you puncture POLYCOTE ECS, clean any oil residue from the area of the puncture. We clean using Fantastic and then a paper towel moistened with Pacer De-Bonder or alcohol or water to remove any remaining residue from the surface. The patch should be 1/2" (13 mm) bigger than the hole on all sides.

It may be difficult to match colors or patterns. When you run into this challenge, you might want to take a different approach. Rather than try to match the color or pattern, deliberately use a black white or silver patch and cut it into the shape of a panel hatch. Detail this with lettering and a perimeter line and it will look like the hatch is supposed to be there. Another trick is to cut the patch into a shape of a letter, flag or aircraft marking.

We recommend using after market POLYCOTE patching material or polyester covering such as POLYCOTE, ULTRACOTE or ORACOVER and the use of a heat iron and soft cloth. Monokote, SolarFilm or V-COTE covering material will also work. Cut the patch with rounded corners. Seal the patch in place with a heat iron set at 250F first and then tighten the patch and the original covering around the patch as outlined in the tightening tip. You may need to experiment a bit with the temperature of your iron depending on the patch material you are using.

To repair larger more extensive damage areas, you may wish to obtain the appropriate POLYCOTE ECS covering set for your model
