Does exposure to heat permanently damage golf balls?

[bunkerputt]

I mean anything significantly above room temp, like 140 degrees or so, i.e. the inside of the car in the summer. A guy at golf galaxy told me not to keep balls in my car because even the tiniest bit of heat exposure affects the distance significantly in the negative. This sounded a little bit extreme to me. I'd heard that water definitely affects the balls, but I thought that hotter balls traveled farther. Does it do damage to the ball when it cools back down? Has anyone else heard something like this?

This site would appear to indicate the opposite to some extent:

I could see extreme heat damaging golf balls, but not locked-inside-the-car-on-a-hot-summer-day heat. Or maybe rapid extreme changes in temperature over and over again or prolonged exposure to high heat or something like that. But I'm no expert. Email Titleist and see what they say.
