So my house has aluminum siding, and along the top of the sides that go up to the peak of the roof, there was (very old, cracked, rock-hard) latex caulk where the siding meets the eaves (see photo). Anyway, removing all that old latex caulk was a major pain in the you-know-what, not to mention my wrist/hand. I finally found a caulk remover that actually worked on it, so now all the old caulk is removed and I am almost done re-caulking. I used 100% silicone because I never want to remove and replace the caulk again. By the time this stuff is ready for replacement, hopefully I'll have moved to a different place. However, now I am second-guessing myself, and I am wondering - did I make a mistake on the caulk I used? The guy at my local hardware store recommended siliconized latex when I stopped by to pick up 1 last tube for the job, but I had already finished almost all of it using the silicone. I chose silicone because I wanted it to be flexible, waterproof, and because in spite of latex caulk being "easier to remove", well, I spent days painfully removing the old latex caulk and it was not even remotely easy. Kinda too late to change anything now, but just for my future knowledge. Thanks!
