I'd be concerned.
Another poster commented that his easton bars don't appear to be clear-coated. I suspect he's referring to the newer ec90 equipes. I have a brand new pair that I just installed, and agree that there doesn't appear to be a gloss coat. Are yours the older red or yellow versions? The current production are all black.
In any event, I think there are some items that just shouldn't be bought used, and carbon bars are at the very top of my list. You have no way of knowing their history or the real reason why the seller is getting rid of them. ANY damage to them, including to the clear coat, can lead to structural failure. And if as I suspect you have the older model, they are probably at least a couple of years old.
I have 3 sets of carbon bars, 2 road and one time trial. All were purchased new. Bars and stems are about the only parts that I wouldn't trust to buy used. Sorry to be a bucket of cold water, but safety first.
