Yes, I've used it extensively. It sands much easier than the 3M Spot Putty. Also, because it's a two-part mixture it tends to be spreadable for a few minutes versus the 3M for maybe 10 seconds. I'm extremely please with the Icing.

Our kids are in TARC and use it for body tube repairs. It can be sanded to such a nice feather finish that it becomes invisible under one layer of paint and allows them to keep their TARC rockets in great shape after dozens of flights.
