If the "Magic Mastic" is anything it is at most interesting due to its claimed thermal bandwidth--- claiming to remain stable at up to 120C (that is nearly 250F). Right now the biggest problem with mastic is not its application or even its stability (carbon is such as good insulator) but its bonding power. It is not that the bond is not strong enough but often too strong. This leaves as the "weak link" the bound between the basetape and the tyre. Since this bond is not a tacky bond: once it is broken it is broken. An idea mastic is thin and easily flows but quickly dries to a sticky tacky paste, has a bond that is less strong than the basetape (sacrificial bond) and with a high melting point--- rims can reach 100C. On the track this is never a problem and we also don't need tacky bonds. Here we want less elastic bonds since their tradeoff is higher rolling resistance. On the road we want a min of elasticicity but with still a large degree of tackyness. With Alu rims the glue can get very hot. Increased stability could be nice--- back in the old days people would often glue a thermal insulator between the tyre and rim. Will this new mastic deliver something beyond what I've seen in industrial glues? I doubt it... But lets see....
