I'm working on sanding and prepping the bottom of my H23 to paint. I was planning to support the sides and lowering the bunks to paint under them. I have read past posts and jave seen pictures in the archives of doing this. But my trailer (original 1985) has one piece supports that can't be lowered. As I see it without lifting the boat off the bunks, are there any other options I can do with it? I am working on it in my driveway.Thanks, Mike
