Hi , if you can find in your country a product Mr Muscle Oven Cleaner or similar , it is a spray on foan and very caustic . The way to use is to place the model on a plastic bag and spray the foam all over it , carefully fold the bag over the model and seal it for about 30 minutes. Unseal and place the model under running water and most of the paint should lift off . Anyt remaing areas can be cleaned with an old toothbrush , or a repeat of the foam . Always wear rubber gloves and eye protection . hope this helps cheers ian
