I have been following this thread with great interest, but have a couple of questions. I have read that hard to reach places can be difficult to cover. Is there a technique for this? Does anyone think that underneath the hood or trunk needs to be buffed out or just left as is after final sanding? Also, what about water spots on the paint after it is all said and done, wax and all. I live in a rainy area and am worried about water spots forming before the paint has cured. Thanks again for all the input from everyone. This thing is spreading like wildfire!!
