Oh man, My tub looks so good right now!!!!!!!!!!!!!!!!!!!!!It looks nicer than the day that I got it. I used the stain that you buy right at arctic spa, I have had it for over 2 years and it is still good. So the main side of the tub where you get in and out of, I sanded lightly just to clean it up and restained. The rest was a light light sanding then washed and dried. then just added the stain. The one side where all the water sits needed a good sanding.Man it looks so good, if only I could get the tub to run!!!!
