Caulking Recommendation

Before painting my 25 year old deck railing, I would like to caulk the joints in the attached picture to give it a seamless look. Joints are about 1/8". I was thinking of using Alex Plus, Big Stretch or one that you would recommend. Thanks for your help.

My go to caulk for painting is 'white lightning' but I seldom caulk deck railings because they tend to expand/contract with temp/humidity changes and IMO an open gap looks better than failed caulking. If I was pressed to caulk it I wouldn't use any more caulk than necessary.

Your deck and therefore your call but that sounds like a lot of effort that will likely amount to nothing with heat and cold expansion and contraction.

My outdoor caulk is Quad, best krap I have ever used.

I too would not caulk!

I did think about the expansion & contraction but I figured that after 25 years it might be less and the caulkings today are far better. I have to agree that I could be sorry when I look at failed caulking. Thanks, as always for your help.

Acrylic latex caulk is the best fit here.
