Re: Air bubbles on heat pad?
Not sure about the air bubble, but I have re-stuck heat pads before. I think if your careful enough taking it off, and don't bend it much, it can be done. Always rather safe than sorry though, so if its really on there good and you're not able to get it off without bending it, I think its worth the piece of mind to get a new one and not have to worry about it.
But yes, I have taken heat pads off and re-stuck them without any problem.
Re: Air bubbles on heat pad?
As long as they are small it won’t have an effect. I did test the air bubble spots in one of mine and there was considerable heat loss in those spots.
