I just returned from a little beach time down in your neck of the woods, Panama City, and my primary devices, the smok DCTs were nearly useless. Any time they left the condo, floodsville. After 2 days I just resigned myself to leaving them in the cool condo where they worked fine. For going out and about, EVODs only (which flooded even, but far less). I wondered if folks who lived down there could ever use carto tanks. I would think a higher VG juice would help. If you have any Boba's or another all VG liquid, see if that helps.
It's too much of a hassle for me for the reasons you encountered. Any rapid change in temperature meant instant flooding and I finally gave up on using carto tanks. Extra wicking in BCC coil heads addresses most of the flooding problems with those, but there was nothing I could do to save the carto tank experience, so I gave up on it.
Hope you enjoyed your visit to the Gulf Coast. We think we live in paradise.
