'Red Volunteer', as with many other reds, *will* melt and slick in hot sun. Try to put it into some shade - at least, afternoon shade. I can't speak to the other reds on your list, as I have not grown them (well, I have 'Ruby Spider' but have not yet had it bloom), but 'Red Volunteer' slicks here.
Blooms on 'Bali Watercolor' can spot, so I would try to place it somewhere the blooms won't get hit with irrigation spray. For that matter, it has been rust prone here, so irrigation spray on any part of it may not be a good idea... use drip or something that won't leave the foliage wet. (How much good that will do you in FL, I don't know...
You may have to (ugh) spray.)
