How would you guys recommend I strip paint from a urethane/plastic rear wing?

The original paint was painted over once already, so I am going to be stripping multiple coats of clear/base/epoxy

Will aircarft stripper damage the plastic?

Thanks for the help

I would use the stripper but take it off of the car first then strip it..you may need to use an adhesion promotor depending on what kind of plastic it is..

The wing is off of the car already....I blotched the previous repaint so I would like to start from scratch instead of adding more BC/CC.

I will use the aircraft stripper and maybe wrap the entire wing in plastic wrap so I get good and even penetration. I will monitor it closely so I don't end up warping the plastic.

I would put some stripper on a test piece of similar plastic before you do this. I had a unfortunate encounter with aircraft stripper and my rubber bumper on my 71 Mustang, it ate a hole in it. I was stripping the hood and some went over the edge and got on the bumper. By the time I noticed, the stripper ate through the paint and about 1/8" down into the bumper.

Either have it plastic media blasted, or do it the old school way, sandpaper.

Keep paint stripper away from urethane parts, they'll swell up like a sponge and you'll have adhesion problems down the road.
Like Old Fool suggested-media blasting and sanding are your two best options. Follow that up with a thorough scrubbing with a grey scotchbrite/water/Ajax cleanser and a good rinse, then waterborne wax and grease romover and it will be ready for any 2K primer. SPI's epoxy really works will on these flexible urethane parts.
