This handheld tool is designed to get into tight spaces like wing roots, intakes, or other tight or hard to reach spaces. It has four resin-like tips which are to be superglued to the tip of the tool, and sandpaper is to be attached to the tip with double-sided tape. I have to admit that at first this seemed like a pain to set up, but it is really very quick and easy. I tested the tip change out by removing the attached tip and prying it off with a hobby knife, and it came off cleanly and in one piece. I then glued on another tip, the one with the triangular point. I attached a small piece of sandpaper with double-sided tape, and then trimmed the sandpaper to match the tip with my hobby knife, and the sander was ready to use. As advertised, it works well in awkward spots like wing roots, as shown in the accompanying photos. I also find it useful in cleaning up areas to be glued where paint needs to be carefully removed.

Despite my initial doubts, the ModSand Detail Sander has found its place in my frequently used tool holder.

Thanks to John Vojtech at UMM-USA for the review sample.
