The foam is very lightweight.  My understanding is that on humid days
(aren't all days humid down there? ;-)    ) the foam can still become
encrusted with ice in some spots.

My own intuition tells me that sprayed on foam, even carefully applied,
may not always stick properly or prevent ice buildup from moisture.
