Just given mine a bit of a spruce up. Quite easy to remove and good clean and respray, they look really good. One side of mine had some broken clips, so it's had a bit of glue fix to get it to hold back in but managed it. £6 for a can of paint was definitely cheaper than £200!
Yep, good old Gorilla glue should be fine. Tried hot glue gunning both of mine but the one with the broken clips wouldn't hold. So, resorted to Gorilla glue for that one and it still seems to be holding.
