Dexter and Lippert both say to use it (thin film) unless the seals have a rubber coating.
I have done some checking, and a lot (most) threads I come up with say they don't use it. Possibly because they have found it too hard to remove the seals when changing them out, and those that don't have an issue weren't commenting. You generally hear more from folks who have a complaint than those that don't.
I know mine were a real bear to get out (the fact that they are the original seals - everything around those wheels was original - probably didn't help). But since you don't re-use them anyway, the fact they looked a bit like an old chew toy wasn't an issue for me. I am inclined to go with what Dexter & Lippert tell you to do - I am using Lippert seals. My feeling is that it is a belt and suspenders kind of thing. And I have no problem with that. The fact that it will make it harder to get them out doesn't bother me. The amount of traveling I do will entail just pulling and inspecting the bearings once every couple of years, maybe even less often than that. I can take a look at the rear bearing when I pull the drum to check brakes, which I do every year, and the front bearing will come out with the drum, so...
Comments?

I change the seals every time that I pull the drum (no matter what). I just put my seals in with a very thin coat of grease. Mainly to make it easier to set them.
These types of seal pullers are a must. Makes the job easy.

If you are going to replace your bearings, it's imperative that you replace the races as well. This set makes that job easy.
