Clever putty is a lightly sticky putty ideal for masking your model in order to spray camouflage patterns. Because of the putty's characteristics sprayed paint doesn't adhere to the putty, making it nearly infinately reusable. The putty can be stretched, cut with knife or scissors and adheres to any surface without leaving behind any residue despite its oily appearance. After use, it can be easily joined together again and stored for further use. The metal container contains about a handful of putty to work with.
