We run 100 8f paradise hives. The bees do very well in them.
I do not like their plastic QX as the bees tend to stick them to the frames, making supers hard to split to remove. We have replaced them with steel and makes life easier.
As a migratory Beek the light weight is good, also when handling supers of honey.
Painting is done with a small roller, 8" x 1"which fits the handle slots, plus plenty of paint for the small surfaces of writing etc.
Spray would be good
