First thing in the morning of 1/1/25 I started applying the Rubio Monocoat 2C black.  Overall, I was happy with the result.  However, with the additional sheen and smoothness of the product, some sanding flaws came to light.  And unfortunately, they were right on the top surface of two of the arms.   Rookie mistake - I should have caught them while I still had bare wood. 

I tried some spot repairs, but was not entirely happy with the results.  I emailed Rubio, and they confirmed my suspicions.   When using precolor, a spot repair is not going to yield the best results.  The fix will be to sand down to bare wood and start over.   I am taking a pause before I do that.  I'm pretty sure it will bug me from now on if I feel those rough patches on the arms, so it's likely I'll re-sand and re-finish the tops of the arms.  I just need to wallow in self-pity for a bit.  😀

Here are a couple photos that I took before discovering the issue.  None of them show the patches, though.  But they're there.

I love how that grain shows through.  These photos were taken immediately after applying the 2C product.  If it kept this sheen, that would be perfect for me.  It dulls a bit to a matte finish as it cures, so I'm hoping that the Sheen Plus product will bring it somewhere near this state.
