There's one time or another that you may run across or even have it happened to is get a cigarette hole in the interior of the carpet.
This sounds like a very diffucult fix but with a little patience, it really is a simple task. Simply trim off some of the carpet fibers toward the carpeted firewall area. Take some clear sealant caulking, the one that stays soft & put a dab on the affected area, place the fibers on the clear sealant & let the sealant dry. It's magic! In thirty minutes, you will be able to drag your fingers over the area & not feel a thing. Magic, NO. Smart, Yes! Just some more words of wisdom.
