[Alberg30] Bottom Paint

[George Dinwiddie]

Ablative bottom paint doesn't really require sanding.  Instead, wet it 
with a hose and use a 3M grill scrubber 
(http://www.home-fix.com/admin/upload/Content/125_scotch-brite.gif) to 
clean the surface and smooth the edges.  Where the paint has flaked off, 
you might investigate why the paint didn't stick.  Perhaps the 
fiberglass has some old wax or paint that needs to be removed.  After 
cleaning off these areas, a light sanding will probably be advisable 
before repainting.
