Be careful of using products with petroleum in them if you are using a silicone locking liner. Those products will degrade the liner and cause it to form a hole in the area effected. It ruins a very expensive component, and really blows to have a hole come up mid ride....you think that liner rubs you raw, wait till you get skin on the exterior cloth. I ended up being off bike for over a year due to a lesion that formed from this same issue, aggrivated by a poor "cycling" trimline.
