Hello,
In your experience, what has been your go-to exterior caulk?
I am looking for the best option that holds up well in alot of sun, keeps water out, and has many color options.
Cheers.

Tommy87: I recently had to pick a caulk for my new siding project. The siding material made it a somewhat easy choice: ASTM C920 elastomeric was required. (rather than ASTM C834 latex) The big box store caulk aisle became much less complicated.
I found this article on line as well..http://www.adhesivesmag.com/articles/83327-u-s-sealant-standards-in-building-construction
It is somewhat out of date...since I think the Class 50 has now been approved in the ASTM C920 group. I ended up going with OSI Quadmax.
