Easy spray-on bedliner removal from plastic?

Anyone have any good suggestions on how to easily remove shitty spray-on bedliner from a fender flare? Previously I did it with a paint scraper, but that took forever. Any good liquid stripping agents that won't attack the plastic?

 

Half a day in a steam cabinet.

I have used wd-40 to break up paint......but this will dull the plastic finish over time.....but could reshine using Maguires....

 

I plan to spray some SEM trim black on it once I strip the bedliner off. I've found that to last a while and look good.

 

I've never tried it with that rubberized coating or a plastic before. But citristrip is pretty mild in terms of stripping agents and it works very well on other bonded paints. I might try it in a hard to see area first or maybe on your ruined flare to see if it melts the plastic. My guess is it probably won't because automotive plastics are usually solvent resistant but can never be too careful

 

Hm ok ya I can try it on a small spot on the bottom first.
The other one decided to go live in the desert somewhere.
Some people say it only attacks soft plastic, but I feel like these are somewhere in between.
