I broke my truck bed cover. It is one of those black plastic undercover tonneaucovers. The plastic broke underneath where the back window side attaches to the bed. I called the company but they don't have a fix for it.
I am considering a fiberglass patch. It is on the underneath side, so I don't care what it looks like.
Can fiberglass be applied to that plastics material? How would I go about doing that?
