Re: Can I save the metal Flake
Best way to find out is to try to fix it. Find an area to do and go through the process in that small part before you do the whole boat. That way you will know what to expect. I'd wrap wet sandpaper around a flexible rubber block, first with 400, then with 1000, then 2000, then compound, then polish. Wax it when it's all done.
The 400 should be used to get the any bumps knocked down, don't go any deeper than absolutely necessary. The 1000 will reduce the scratches from the 400, the 2000 will refine it more, the compound will start it to shine and the polish is to bring up the shine. All wax does is seal it in.
If there is still clear on top of the flake that's how to remove the corrosion to repair the surface.
