John,

The keel strip you'll have to make yourself, but it's real easy to do.

Get some good epoxy, like MAS, Raka, or West System, and put an 
appropriate amount of the resin in your mixing cup. Add fumed silica 
(ALWAYS wear a respirator when working with this stuff if you value your 
lungs) until the resin is thickened enough to be the consistency of a 
thick latex paint, add graphite until it turns solidly black, and then 
add hardener and mix for at least 90 seconds. You can add more silica at 
this point if you think it needs it.

The final goo should be thick enough that it won't run once applied, but 
thin enough to be just usable, too.

Surface prep is easy. wash the area with acetone, sand with 150 grit 
paper, and mask it off. Then you're ready to apply. Put it on smooth and 
as thick as you want, and if you want the surface really smooth, you can 
put release film over it (Same stuff you'd use for gelcoat) and remove 
once the epoxy begins to harden. Myself, I sand it, or drag it up a few 
beaches -- same effect. I haven't noticed any drag from it being there, 
but then again, I don't race either.

My last strip is 4 years old, and still mostly intact. (And I didn't use 
the graphite - it will last longer if you do). Great stuff.
