I may be doing it wrong but when things need resealing on my trailer's rubber roof, I pull off any loose stuff and just re-seal over top of the other still adhering stuff.

I used decor self-leveling sealant for years, it works well, but switched to eternabond tape, for seams on my rubber roof. They make a product EternaBond® AlumiBond tape for aluminum repair. The eternabond tape is good for 25 years, not sure about aluminum roofs, but if their Alumibond is half as good as the Eternabond then its a winner. It would appear that it would work well.
DanoT is correct, for reapplication, you just remove the loose stuff, clean the old sealant well and reapply. Dicor has a 1-3 year life.

I have had the best luck with 3M 4200, but it is not self-leveling. You have to tool it into place, and it does not provide a smooth finished surface. It seals very very well though.
For self-leveling sealant, Sikaflex 715 is the best I have used. Dicor doesn't hold up very long in my experience.

I've have good experiences with Dicor. Never tried Sikaflex, but I would go with either of those two.

+ for Dicor here too. I have mainly used it on rubber roof, plastic flanges - but also noticed it bites really well onto clean metal.
