I have been installing new clapboard siding on my house. It is primed finger jointed cedar. The one time I had a friend help me he questioned my method of caulking. What I have been doing is installing the lengths then applying a bead of caulk to the ends where they meet the trim boards (I think that's what they are called. Basically, these are the long boards that run from the top to bottom of each corner) then finger smoothing the bead.
He suggested that I should be applying a thick bead of caulk, then apply the board squashing the board into the caulk.
Is there a preferred method? And is it one of the ones I listed?
