Hmm...yea, some damage is possible, and then with a half season of pounding, it could delam at an inopportune moment, like right before an AWT heat or at Pistol or somewhere remote. It's not like boards last forever anyway, so to have a #2 ready or make it a #2 seems like a good idea.

Hey Marty,

Sounds like your looking for an excuse for a new board Smile

Haha. Smile. Well, Not quite because I'll want the same board. But I could use some justification for the impact on the already tight storage I share. Smile

Still not satisfied, I did some further research. Smile Using data tables that show how much air pressure changes for a given change in temperature or altitude, I was able to validate the claims that damage is more likely to occur from heat in a car than from air travel. I also found additional information about pressure in cargo areas of passenger flights that indicates the pressure is similar in cargo as in cabin--equivalent to about 6,500 feet in altitude. So let's say the range is 6,500 - 8,000 feet. That would mean a change of about 3-4 psi on ascent/descent during a flight. I also found tables that say for every 10 degrees Far. in temperature change, the air pressure changes about 1 psi. So the pressure change on ascent/descent is about the same as a 30-40 degree change in temperature. So you can see that lots of people are probably leaving their vent screws in place and undergoing 30-40 degree swings without much issue. But if you add the additional 30-40 degrees of heating in a closed car, you are doubling the pressure change to the equivalent of a 60-80 degree temp change, or also about double that of transfer in cargo on a passenger flight.

The only epoxy board I ever had delam, delammed from being in a hot
vehicle. I still remove the vent plugs when I go from sea level to a mountainous region though.
