If you can't find any Modelstrip you can use Mr Muscle foaming oven cleaner. I used it recently, sprayed onto a wagon body in a sealed plastic box and left overnight. It took off 30year old factory paint and never touched the plastic. I used to make my own paste from powdered Ronstrip but I think it's been withdrawn due to health issues.
