Got a Wizand V3 with lose bottom side. Opened it today and found that this board has no sandwich construction. The previous owner maybe let it in the sun for some time, the styro core under the laminate was crazy burnt out 1-2cm deep. This is a total damage.
Man that's nuts. Hard to imagine what kind of abuse would do that. Mine lives on my boat dock year round from 15-108 deg f. Plus the gazillion hours I have on it. I'm carefull not to bang it on anything, but that's it, No issues.
See it all the time on dark boards especially close to car windscreen / dashboard
Dark boards in sun are just a silly idea but they persist in making them....
Damn super surprized it is not sandwhich construction. I have found the sling shot boards very durable.
Moz: do you think its just the suns heat, or some kind of UV damage
^^ The early Slingshots are not sandwich up front on the bottom, which is ridiculous for windfoil, but they learned the lesson. The top is all sandwich BTW
The issue here is simply heat - the sun heated the dark skin enough to melt the styro core. Vent plugs are essential to prevent delam, but it doesn't mean you can just bake the board in the sun..... external laminate heating can do exactly what we see here.
So why do they make boards with dark paintjobs...? Who knows.....
Most often see that damage with racks in a van just under the roofline so the board is within inches of the steel roof, or a SUP in a car with nose on the dashboard ...... I repair boards with melted core like that allll the tiiiime.
The guy who owned this V3 wizard previously had a V2. This board also came loose in the bottom after one season. It was white with yellow and orange. Possibly the sun is more dangerous at this high spot (Silvaplana) than at sea level. I figured the UV would be the bigger problem there than heat

Here in Texas, about 100 meters above sea level, it's the UV that kills surfaces that aren't covered. Gel coat on boats etc. Even boat covers made from sunbrella fabric (great UV reistance) will come apart IF the sewing thread is not UV resistant. I could certainly see heat from direct sunlight on dark paint for extended periods causing issues though. I've had several boats over the years and only choose white. Anything darker will burn you ass. 
That is some insane heat damage, it's a shame someone would be so careless with their equipment.
My Wizard 130 is 3 years old and it's been in Texas (100-105 degF) and Florida (90-95 degF) and I have never seen this issue, probably because no one lets their boards bake in the sun all day 
Had the same problem on my wizard 125 few years ago, it was my fault becuase I left the board inside the car (black car) for almost a week in summer time, where I live summer is very hot,.
Never again.
Like this Moz :)))
Also what do you think about those goretex vent plugs. Heard a rumor that salt can stuff them up...
