Any experiences with spray on Opsite?

I just came across this product online and was wondering if it’s a suitable alternative to the Opsite Flex tape, for those who apply the Dexcom sensors on top of an Opsite film patch, to extend the time in which the sensor adheres. Seems interesting, but I wonder if it is as long lasting as the film.
