Love it or hate it, it’s an important part of building. From addressing joints to polishing clear parts, all are some forms of abrasives. And since sanding covers a wide range of areas, there’s a matching range of sanding options. There are myriad types of papers one of my favorites is sanding sponges. (3M softback😉) Another favorite of mine is a flat surface with a piece of sandpaper glued to it. It’s wonderful for flattening two mating pieces to create a joint that visually disappears when done correctly. Finally, sanding sticks. My favorite source is nail files from beauty supply stores. Don’t worry, you don’t have to go to a beauty supply store to get them. Shop online! I’ve found they are far less expensive than the “Hobby” brand ones. But they will not meet all your sanding stick needs. Companies like Alpha Abrasive and Flex-I-File have tons of specialty products to get to those hard-to-reach areas. And if they can’t meet your needs; you can always make your own. With a box of tongue depressors, some spray glue or double-sided tape, along with your favorite sandpaper, a straight edge, and a hobby knife, you can make any shape you wish. Keep busy and happy modeling!
