For seven years now I have used Griot's products and Meguiar's carnuba on my coach. I've used the same on my cars for many more years.
For the delamination, I tried Steve and Forest's methods, I couldn't get a good bond, but in the end, took the one troublesome door off the frame, removed the 3M tape (difficult but was worth it for realignment). The key is accurately marking where the door is on the frame (I used a black marker, once the tape is removed, you don't have a reference point. If the door is not perfect on the frame, it will not align and may hit the adjoining bay doors). No problems so far one year in.
