[frers-list]re: Bottom Work VC Offshore

[Bill Thompson]

Hi all,

I've been using Petit Vivid White - Rod's right - not avail in Canada due to environmental regs.

Sanded hull back to original vinyl ester last fall, and (if winter ever ends here in Montreal) have to:

Fair keel and rudder (hull is perfect)
Barrier coat
Have been planning on VC-17 as freshwater racing finish/antifouling.

Anybody have suggestions as to choice of materials for each of these operations?
