We're 3-4 years out from a full exterior repaint.

In the meantime, this extra-sun-exposed side of the house seems to have some water penetration (I think that's cedar oils coming out?)

Would, weather-forecast permitting, this be a good course?

• Non-aggressively removing some of the old caulk with a razor
• Wiping down with a dry rag
• Putting white Sascho big stretch in/on the vertical gaps
• Gently tooling with a went sponge

I was thinking the gaps were too small for OSI Quad max, but I've never done exterior caulking / this is all from googling, so idk what I'm talking about.
