I first repaired my roof in 2023. I had to rip all 4 factory seam seals to see where the leaks were coming from. I saw that the metal itself had been separated in some areas. I used 4200 Marine Grade Sealant the first repair. However, I recently noticed that the sealant was coming off! My guess is that the sealant didn't cure the right way because I used pools of it.
In this video, I clean the old sealant off, do some rust prevention, and re-apply a different sealant: Dicor 501SW- 1HAPS Free Self Leveling Lap Sealant
Wish my roof luck!
