What’s the best way to patch a tear in a siliconized Cordura pack cover?
Submitted by – Roger – Los Alamos, NM
Grab yourself a Sil-Fix Sil-Nylon Repair kit for about 7 bucks. It includes Sil-Fix adhesive, several patches (for backing larger tears and holes), a brush, and a detailed repair guide. From there, it’s really simple. Just paint the Sil-Fix over small holes and let it cure for at least two hours. For larger wounds, place an adhesive patch on the back side and paint over the whole area with the adhesive, extending at least 1/4 inch beyond the edges of the hole. You can then remove the patch after it has dried or leave it in place for extra insurance. This a permanent, waterproof fix that will render your pack cover as good as new!
