As a Detail Sander, I have mixed feelings about the MultiMaster. Used on bare wood, it works as stated, great for detail sanding projects. It's compact size is a definite plus when working with small areas and corners. It is well balanced, easy to control, and does not feel clumsy in hand (this attribute tends to decline somewhat when a dust extraction hose is attached). That said, when it comes to sanding areas of detail that have been painted, I have had a different experience. I have yet to find a satisfactory grade of sandpaper that will not immediately clog with paint. Aged oil based paint will come off as dust if you keep the tool moving around on the work surface, but it will clog the paper on the points and edges much too soon. Latex and acrylic based paints will, with the heat from friction of the moving head, turn to a plyable goo that fills the spaces between the grains of abrasive faster than you can say "Holy C**p". Even with turning the paper around a couple of times, those little triangular pieces of paper are too expensive to toss out every minute or so.
If anyone out there has a solution to this problem, please respond.
