Jamming Sunroof

You know that the joint for the surrounding seal is on the back edge, well this is where it's mostly been "jamming up", being just a bit too "proud" and making it tough to fully retract (and slide) and I suspect this is the sort of problem most people have.
Last November (really was that long ago!) I was trying to retract it one time and it was so tight that one end of the seal started to peel off! So I thought I'd best leave it 'til the warmer weather the following year before messing with it any more 
Well finally got around to looking at it today and would you believe that actually it now retracts easier than it's ever done. Almost as though the (really small) loose flappy bit is making it easier by moving out of the way or something.
I was going to try gluing the bit back on or something but now I'm not sure whether to leave it if actually makes it work better - decisions decisions .... 
Looking underneath it appears to be glued onto the metal frame, and the frame is a bit rusty at this point. So I'm guessing if the rust bubbles up this forces the seal outward thus making it tighter in the roof hole. Mostly just guessing at this stage

Yes that's quite right Mike,they all go like that,the corrosion expands under the rubber and tightens things up,bloody nuisance 
GOZZ.

So my surmise was correct, ta
Only other possibility I can think of is sanding a bit off the outside to compensate (?)
I'll see how this goes for the time being, it's been alright over the last Winter so is still keeping the weather out

Hi Mike had the same problem with my sun roof, rust expanding it side ways, I put silicon grease over the seal to make it slide better. I think the water gets between the seal and the glass, when it pools on the roof, and rusts the groove it sits in, the seal that is. I hope if I put enough grease on it will keep the water out, so stopping it rusting. On my Granada scorpio it got so bad I had to change the sun roof.

Yes that makes sense. Maybe apply a bead of something around where the seal meets the glass?
Anyway tried it again today, just in case I was imagining it , still works, fink I'll leave it for the mo

if youre careful you can slip the backside of a blade under the rubber; working round the seal you can run some silicone grease into the space to make it watertight..BUTyou dont want to lift the seal too high as it wont reform after having been in one shape for 10 years...try a small section ....since i did mine a year ago i see, whenever its rained, a nice pool of water on the glass going nowhere...
