Older fibreglass boards may, but it would take a while.
The bags are more about impact protection.
If you see a bag with silver film on it, you may think it is to stop UV: is
isn't. It is just to keep the boards cool as heat *can* damage epoxy
boards.

Bottom line is that heat and UV are bad for your gear and exposure to either
should be kept to a minimum.

Now just have a car big enough to carry 3 boards, 2 masts and 6 sails that
seem to live in their permanently all summer.
236cm long EVO's help in that regard also.
I asked for (and got...) a regular surfboard fin box on the
board. As an afterthought, I phoned him up and asked him if it
would be strong enough for the intended use (16" slalom fin, 220#
rider).
To make a long story short, I should *not* have asked such a
question of him.

"Look dude you drive thousands of miles with plastic headlighs and
glass exposed to flinging rocks, those things last fairly well, and my
boards are stronger. So go sail hard put the board on the racks in the
proper way, no straps cutting rails, (Parton had sharp rails) get
home, love your wife and family, have a beer, eat well and sail
tomorrow. Grinding sand in a bag, can do damage too. DO what you think
is best"
I always feel that unbagged is better, unless a whole bunch of other
gear is banging against the board. which is hard to understand and
results in rash. In fact I have a trailer and often strap a bare board
to the car racks just because it is so much gentler to the board. UV
and vent screws are not issues. Texas heat may be different because at
somewhere above 140 degrees Epoxy starts to change, but in general as
long as the interior pressure of the board is set via vent***"as
hot" or "as cool" additional heating on the roof is not gonna hurt.
Now, lay a garbage bag on your board in direct sunlight...that is a
different thing.
OR
close the vent in Alaska at -40 and 4 days later sit in Walmart
Parking lot Corpus Christi you may want to vent your board. (do it so
you can bring a pound of water back to Alaska inside your board.
Timing is everything)
UV can kill raw resin
Paint or gelcoat is an impervious barrier to the stuff underneath,
although sometimes sacrificial. EVA will fade and accesories will
degrade in UV, so do we. Use the same prudence.
