sealant for siding

[Kodiak]

need to find a good exterior sealant for my lp smartside and trim that i am putting up this weekend. I am going to need something paintable. i was going to use osi quad but it says it isnt to be used for expansion joints so wouldnt that take them out of the running for the joints and where the siding joins the trim 3/16"....?

My choice would be Vulkem caulk. It's a poly-urethane base and paintable.

Second on the Vulcum...it's the only thing to use on Smartside

why is it the only thing to use, cause of its flexibility?

Paintable, flexible, durable, and less shrinkage.

is it at menards and home depot, i imagine it is, i have used the osi quad before, i heard it is not as good as the vulkem
