New Foss Foam Rudder - Prep

[szymek]

I finally picked up my new foss foam rudder:





This rudder is for my Catalina 25. So rudder is mounted on the stern and bottom half is in water only. Should I leave it as is? Paint it - if so just use antifouling or some sort of barrier coat then antifouling.

Any advice would be much appreciated.

You were probably warned by Foss Foam that you should not use any dark colored paint - antifouling, etc. on the rudder as the foam core can bake and shrink.

A barrier coat might not be a bad idea to keep the rudder from absorbing water since the surface is only a gelcoat over the FRG skin. There are quite a few brands of barrier coat and for such a small job then I might suggest the Pettit Protect available in quarts.

If the boat is going to be left in the water with the rudder attached then I might suggest the new Pettit Econea paint which comes in white and is available in quarts.
