are you just doing plumbing? if so it should be fine. not familiar with that one. I always use the wet and dry blue glue. and used the hot glue its blue and for wet/dry apps.
Yes Christys is fine. Christy's red hot is one of the better glues for flex pvc. It is very similar to the Blue wet or dry stuff in that it has extra solids in it, just a different color.
