I'm about to paint the bottom with another coat of Interlux VC 17 M.
The data sheet is a bit ambiguous. In one place it seems to say that
old paint should be sanded. In another is says sanding is not
necessary when the old paint is VC 17 M.

I think I remember the yard that put the VC 17 M over the VC 17 that
came with the boat saying that all that needed to be done is go over
the surface with a Scotch Brite pad.

Anybody out there successfully recoated with VC 17 M without sanding?

My wife used a Scotch Brite pad on VC17 last week and put on VC 17M
over it with no visible problems. Looks fine, if a little thin. A
second coat will be needed before launch.

YMMV
