The PM3437 Prep Pen from ANEST IWATA Australia is used during the process of paint surface preparation as it is an alternative to folded sandpaper. The preparation pens enable the user to scuff, sand, de-gloss and clean surfaces rapidly and simply. They are suitable for removing rust from paint chips or hard-to-reach spots, and come equipped with a refill cartridge inside the handle.
Prep Pen features glass fibers within the cartridge that are stronger than steel yet finer than human hair. The glass fiber cartridge can be extended out of the surface preparation pens when they are required, but can easily be retracted when not in use.
The Prep Pen operates similarly to a pencil point sand blaster. The minute glass fibers reach into small recesses that sandpaper cannot because it is too rigid to directly contact and clean contours of inside edges.
