Hairline settling cracks in block mortar line

I have a block and stucco house in Florida that needs to be repainted. In examining the walls for preliminary prep work, I noticed that there are several hairline settling cracks along the block mortar line. I would like to know if there is a flexible product I can use to fill these cracks before I paint that will not dry out and re-crack in time. Any and all suggestions welcome.....thanks, Buz

When it's not a big enough crack to warrant being patched with mortar I normally just use acrylic latex caulk. If you just fill the crack it shouldn't affect how the stucco looks.
