Hello, So I washed the roof of the trailer today. I noticed two small spots where the caulk has cracked (about an inch) in the top corners where the roof meets the sides. The cracks are in the middle of glob of caulk itself (if that makes sense). I don't currently have any leaks but hoping to keep it that way. The rest of the caulking looks to be in really good shape. For these small areas do you guys notch out the crack, clean really well with rubbing alcohol and fill with new caulk? Am I on the right track with this approach? Thank you!
