Re: bilge paint color

This is what I found on the bottom of the bilge stringers, which apparently had never been re-coated?

Re: interlux 2000e epoxy primer

In the 'hull construction' forum, May 30, you asked about these opening seams.

Re: open seams in new 5200 Bottom

My guess is that change in your shop's humidity levels allowed the planks to shrink? CPES is a semi-permeable membrane, not a moisture barrier coat, it does slow, but not stop, moisture movement. It's main job is to penetrate and fill 'abnormal porosity' like open grain and rot spore tendrils. It's ...

Since he is 'repairing small sections' at the stem and garboards, I recommended that he stay with the original boatyard bedding compound and canvas so that it moved like the other 90% of the bottom he is not re-planking. 5200 would also work but might make stiffer areas where used.

I'm a bit confused by your use of the term "Cap Rail"? A Cap Rail is generally a "CAP" to a raised bulwark, 2" or more above the deck. A "Toe-Rail" mounts directly to the deck. If you can post a photo of your original installations, perhaps I can help with the least messy way to go about the new ins...

Re: Removal of a broken engine plate drive screw

Hey, If it's even possible to 'break' a 3/16" long rivet, what would be left is tiny. If you are going to try to 'drill' it out, you should use a "Reverse-cut" drill bit, so that it unscrews the super-tiny bit of the rivet left, by its own threaded rings. Be VERY careful to not drill into the cast i...

Yeah, you should scrape that excess off. Its meant to soak into the surface "abnormal porosity", not puddle on the surface. A thick surface layer could be a weak link in 5200 attachment.
