Reviving and old issue I had with this car which operates similarly to the aquarium action car.
I was experiencing an issue with the revolving film strip sticking to the background of the scenery.
Using talcum powder was a short term solution that worked for a while. Did not try the silicon sprays do to the interaction with plastic.
I finally found a low tech solution instead of opening the car and stripping the screws to pry the film strip from the background.
On the bottom of the car are small openings that I can fit a small precision flat head screwdriver in and gently pry the film strip back. This seems to work for a few months and then it will stick but it beats having to physically open up the car and go crazy trying to line up the chewed up screw holes.
Just wanted to share this tidbit.
