You can use old or junk-mail plastic credit cards as spatulas for spreading fillers and putty. They can be cut to any size or special shape. I also use them as a flexible sanding stick by gluing wet/dry sandpaper to them and cutting them to the desired size or shape. Now those unwanted mailers aren’t junk mail — they’re modeling supplies!
