Fill my gudgeon nut recess holes!

[mtompson]

Hi
When I uncovered these plates the recesses around the nuts where filled with a fairly hard but not too difficult to remove filler. The plates are then faired over with an epoxy filler.
I assumed the filler wasn't epoxy as it was fairly easy to remove.

Any ideas for an epoxy compatible filler I should use here? I thought it could have been a sikaflex, but not sure.

cheers.

I think you're right that it was sealant, something to eliminate seepage into the rudder. Normally, you'd put some into the holes, and on the threads of the nuts, and it should squirch out when you tighten them. Then, you can smooth it, to sort of fair it.

You really don't want a tough epoxy which will be extremely difficult to later remove for service. Something like Bondo is OK for this simple fairing operation.

(1-Part) Polyurethane paint / cotton putty may work fine too.

Test the putty first as not all paints dry well in a putty.

I have also used polysulfide goo under epoxy and it worked fine.

An epoxy surface will go over anything except silicone. You should use the easiest filler to remove later, ie not something like 5200.

Thanks everyone, great stuff, any reasons sikaflex 291i might be wrong? I haven't had to dig that out of a metal hole before, but I have some handy.

A house is but a boat so poorly built and so firmly run aground you would never try to refloat it.

291 will be fine IMHO. I have used 291 and West System epoxy together wet on wet successfully. That proves to me that they are compatible.

Then blow me offshore, matey?

I may require a cold compress.

Why do you even need to fill it in? just leave it and the bolt heads will be visible when you next haul. That way you can inspect them. If you just want to stop growth, pack the area with an oldschool betting compound like dophinite. that way you dont have to fight it too much when you need to remove the bolts later.
