Just as an FYI, if you are going to add caulk, make sure you do not use silicone.
There are several schools of thought on this matter...I subscribe to the "no silicone" regime.
IMO a polyurethane, tri-polymer, or polyether sealant will adhere better to many different substrates. Generally they are easier to use/tool than silicones and fairly easy to clean off. Yes, there are some very good silicones but silicone is a contaminate...it is difficult to remove. All sealants will eventually fail and need to be replaced. Once silicone is on a surface, you are pretty much stuck with using silicone without some serious cleaning and prep work.
I believe most manufactures use polyurethanes at least where exterior sealant is used.
