After reading for a half an hour I just need to ask for some help from the pros.

I am gluing up four 1.5 x 54 inch slats to a very gentle curve (sleigh rail on crib). I have very small gaps at the curve from the table saw not cutting the 6 degrees precisely. The boards come together nicely but im worried about smoothness.

Which glue is going to be best for luting and finishing very small gaps in this arch?.

thanks everyone!
