I think that seems most likely too-- since the flaking is occurring mostly on the roof and on the hood, which would be the parts most exposed to the sun. It's probably not that expensive to fix if you're worried about it. If you got a cover for when the car's in the driveway you could also prevent further damage.
Sure. In truth I don't understand a lot of car talk either, but thankfully a lot of this stuff isn't too difficult to look up and like I mentioned, I can usually ask my dad about it when he's in town.
Thanks!
