Here is a before and after picture of my Astroglass. The finish on it was heavily oxidized and I thought I would have to gel coat it or paint it. Most of the top cap felt like 100 grit sandpaper. On the advice of my neighbor, his brother, and 2 painters at work, I got most of the family out in the driveway with 2 buckets of slightly soapy water, 500 grit wet paper and a little elbow grease. Only took about 45 minutes to sand it down. Then went to the 1000 grit and did it again. That took less time. I rubbed most of it out with the buffer and 3M liquid rubbing compound, but by the time it came to the 3M Finesse it II, there was too much dew settling down on the boat and it kept balling up. So, my 12 year old daugher helped me hand polish it until about 12:30 in the morning! The second picture is before we put the carnuba wax on it. You can actually see and count the louvered shades in the windows across the street. After the wax was even better. Now I have to do everything under the rub rail.........
