What's best to coat the inside of a newly drilled rudder hole so the foam doesn't soak up water... ?

Just use a q-tip and paste silicone in?

Should I route out some from so I can build a layer of silicone... then insert the bolt?

Not that complicated, but figured I'd ask..... thanks -Rob

I use epoxy and a small brush. Apply a couple coats and fair. Silicone would work if you never take them off again.

Don't use silicone. It'll never hold up to the wear from repeatedly raising and lowering the rudders.

The best way would be to drill an oversize hole (one or two drill sizes larger than the rudder bolt), fill the hole with epoxy resin, then after the resin cures, drill thru with the correct drill for the rudder bolt.

I have only ever filled and re-drilled holes in old lexan rudders. My stock 87 EPO rudders have never needed bolt hole repairs of any kind. May I ask then, how were the old EPO rudders sealed at the bolt holes, and are these new rudders constructed differently so that the inner layers of material will be exposed to water intrusion, more so than the older units, when they are drilled ??? Hope I never have to know, but we all know you could break a rudder the next time you hit the water, so this thread made me curious.
