Flexwatt Problem, need help!

Ok, so today I was putting on a piece of showerboard that had the flexwatt attached to it, for back-heating my rack. Anyways, I totally wasn't paying attention and put a small tack-nail through the flexwatt, now my question is. . . Can I just patch the hole with a piece of foil-tape, or am I gonna have to order new flexwatt?
Thanx in advance,

Where is the hole? It should be fine if its on the edge. Dont use foil tape, use electrical tape.

the hole just skimmed the very top black line on the flexwatt, I'm not sure if it punctured the black line, or just skimmed it.

Just put some electrical tape on it regardless and itll be fine.

Great! Now I don't have to wait another week to move my BPs in to there new rack! Thanx for your help. just use the black electrical tape right?
