Well, I have the same issue. I have been using DOW Scrubbing bubbles. If you read the Diamond Shield web site, they state that it is actually slightly porous, or breathable. They say to clean it with Alcohol.
The Scrubbing bubble is slowing working. I started to try to peel it off, but that was not looking good. I think it has to be a pretty warm day, in the sun, and then there will be a lot of glue clean-up.
Scrubbing bubbles is what I use on my boat seats and it makes them look like new and does not dry them out like bleach products.
