My father in law got a "Paint Shaver". I don't remember the name of the manufacturer, but it was out of Massachusetts, and that is the actual name of the product. We used it on a house we were painting. We had scraped, power washed and tried everything else, but always, witin a day or so, more old paint was peling off. Finally we tried the paint shaver and WOW! It took the old paint off right down to the wood. If we'd started with it instaed of just finishing with it, it would have taken about a quarter of the time! I highly recommend it! Good luck!
