I made some test finger joints out of cedar and glued them last night. I hand-planed the joint today to see how it looked and it failed! The temps went to 45 last night. The glue is relatively new. I didn't clamp it but you had to wriggle in the piece because the joint was fairly tight. I've rarely worked with cedar. Is it resistant to yellow wood glue?

Fresh unweathered cedar is "resistant" to most glues. Polyurethanes
like "gorilla glue" work inmany cases - and wiping down with acetone
before gluing can help as it removes the natural oil from the
surface/fibers. The right moisture content (less than about 15%, but
not too dry (like less than 5%) will let normal wood glues cure
properly
