Slight correction........
3M 5200 will skin-over and
start to cure in 24hrs. After 7-days, it will cure enough to work with safely. It takes 90-days for 5200 to fully cure. Once it is cured, it is the devil to remove so be sure that this is the path that you want to take. IMHO, 5200 is a permanent attachment. If it ever has to be removed for some reason?????????? the removal process will likely cause damage.
Another good solution is eterna-bond:

Again, it's pricey, permanent and not real attractive. However, it has been proven over and over again to be very effective in permanently solving roof leak issues.
IMHO, 5200 is the more attractive of the 2 (if used properly) but the eterna-bond may be the better solution in this particular case. You will never have to touch it again......but you will have to look at it....
