I'm sorry to be reviving this old thread, but I'm convinced that there are other Elise owners with the same problem with their window seals.
I also had the "bobbly" seals and refused to pay 2 x 160 euro for the original Lotus OEM parts, but now you can buy replacements from Elise-shop.com:

I do not have any affiliation with Elise-shop (other than being a satisfied customer), I just want to share the information with other owners who are looking for an alternative.
I haven't installed mine yet, but will post back as soon as I have.
Cheers
Steve
