Well, I got an email back from my tech, it reads:
"I got a separate opinion on the putty. I'm being told that it's normal on some units to have that happen to it the first few times you run the slides in and out. It is actually access sealant around the window that's breaking down from the heat. You should be able to wipe away that access without any real issues."
So, if anyone else has this issue, you can direct them to this thread. It seems Mark was spot on with his theory. I cleaned it away using both WD-40 and Goof Off. Both seemed to work about the same and quite well. I closed the slide and opened it again to see if it would continue to do it, and to my disappointment, I now have to clean the slide again, but not as much this time. Thanks guys for the help and I hope we all have learned something here for future reference.
