I haven’t had one blow off in years, but I still put on hearing protector (nice for the compressor noise anyways), safety glasses and use the prestaflator, going slow in short bursts, and slowly working up to ~40psi
And yes, I also use the schraeder side of the Prestaflator on the empty valve stem.
Besides using dedicated valve stems, I also drill a large hole in all the inserts (much bigger than the valve stem base), so the insert sits nice and flush in the rim, and air and sealant can flow freely.
