Umbrella seals should not rub the inside of the springs at all, if they fit right. Also, if you use them, take the sheetmetal deflectors off the tops of the springs, and don't use the "O" ring in the groove under the split lock. Doubling up on the sealing like that will result in the guide getting almost no lubrication, and wearing out in a hurry.

Edit: I just re-read your post and saw you're using double spings. The only thing that will work with them is the small teflon seal that grips the top of the guide, and those seals require machining the guide for a correct fit. Don't attempt to use the umbrella seals at all!
