Final epoxying of the hull, and something I didn't expect

Happy Ides of March.

I put the final coat of epoxy on the hull.

Before doing that i cleaned the night's dust off the hull using a damp rag to get a nice clean boat.  I was surprised when the boat has been dried off to see that the graphite-tinted epoxy had been scuffed by the rag, but unevenly.  So.... when i re-coated the hull OR THE LAST TIME YAY!!!!!!!!! i ran the epoxy over the graphite-coated part of the hull to even out the colour.  Not entirely successful, as the unevenness still showed in a few places.  Just another reminder of my skill level :(.

Tonight is the final coat on the deck and blending into the hull.  After a few days to cure fully, Sunday should be varnish time.

Getting dirty

March 14.  Happy Pie (or Pi) Day!

Last night i finished the second of what had better be two coats of epoxy mixed with graphite powder.  I say "had better be" because there was just enough graphite for 4 3-pump batches of epoxy, and it took one batch to do one coat on half of the boat.  Yay math.  Any light spots will have to get covered up with pigmented epoxy.  Yay makeup.

One thing I'll say about black shiny epoxy is that it shows every single mistake, regardless of how i tried to fix or hide'em; that's mostly spots where i sanded the hull a bit too aggressively or had to fair away a bit more wood than i would have liked.  But it looks really cool.  And if the manufacturer's claims are right, it makes the bottom of the hull much more resistant to the kind of deep gouges I dread.  They claim you can drag one of these babies through a parking lot and while the graphite may scuff, that's as far as it goes.

So, tonight will be:

Putting coat #5 on the lower coamings

  • Sanding as much of the interior as i can reach
  • Maybejustmaybe doing a final epoxy coat on the deck OR the hull.  
  • Glassing my second pair of top coamings.  Somehow i assembled and glassed the original set without realizing that one of the coamings had a part number stamped on both sides, such that once the glass was on there was no way to conceal that stamp other than to paint the coaming or use pigmented epoxy, both of which ideas seemed stupid to me.  Oh well - just add it to the extras.
