3M has different types of mounting tape with some being quite permanent. There's also some velcro tape which has been reported to do well in high heats. Sorry I can't remember which types these are but
@Dashmellow knows something about the subject and may be able to help.
For 3M tape to work at it's best your windshield has to be spotlessly clean where you stick it. You also need to apply the mount only and leave it in place for 24 hours without the cam- this allows the tape to achieve a full bond which it won't do with the weight of the camera put on it right away.
