A recent thread involved varnishing wood, and how it let UV rays through,  
which is what degraded the wood, which is what caused the varnish to  fail.
 
1.   So, I have a set of oars, new, and I am wondering about a)  painting 
them  b) varnishing them  c) leaving them natural.  I  don't know what kind of 
wood it is, kind of lightweight, not oak or  anything.  The last set of oars I 
had were irregularly oiled, 20+ years  old, and, although a bit weathered in 
the grain, not compromised in any  way.  Varnish them, keep them indoors as much 
as possible,  and revarnish them every couple of years.
 
2.    And, what does the UV thing have to do with  shingles?   I have cedar 
shingles on the house on DFI, but no one  ever tells me that I should paint 
them.  That's because you  shouldn't paint them; one should stain shingles to get 
the maximum life out of  them (you don't want moisture building up behind a 
paint film, as opposed to  letting it out through a non-film-forming stain. You 
could also leave the  shingles bare ("natural,") but that gives them no 
protection against UV or  moisture, and they won't last as long.
