great tool
needs a bit of practice, but works really well (I had micron 350 on it) I scrape everything down to the gelcoat and then the finish with the random orbit sander. Do all the work so I can then coppercoat. The whole stripping is shit (I tried marine strip). that works to a certain extent, but then something still gets stuck, you still have to scrape, and it makes a huge mess, with this scraper everything really goes into the vacuum cleaner! great great great, but no illusions, it's hard work!
