White cloudy film on inside groove of an LP

I received two new albums from an Internet music retailer which are from Simply Vinyl. Both of these albums have a whitish clear film on the last track on the second side that reminds me of a coating. In fact, I thought that it was a complementary coating from the record dealer. Unfortunately, the coating has a very crunchy dirty sound when the needle gets to it. It is very frustrating. I talked to the dealer who said that he does not have a clue of what it is. The rest of the record plays and sounds fine. Has anyone else had this experience? The last time that I went to Ambrosia Audio I showed it to the guys there they have never seen this before. I have even tried to clean it with window cleaner. It is just odd that it is on two records on the last track and into the out grooves. Can anyone help?
