2) I do not know what is meant by 'top seal' since that is not typical water heater part.
Does you product manual show a top seal?
Add comment and describe the top seal and add what it does.

3) Attach a photo.

Replace rusted tank

Prevent rusted tank.
If nipples are leaking, and they did not leak before, then tank has most likely rusted out and needs replacement.
Cause for rusted tank is depleted anode rod.
Inspect and replace anode each 1-3 years.

Make sure any water valves (Cold or Hot) for water heater are not leaking first. Gate valves may leak at the packing nut over time and drip on top of tank. If water is leaking from the top of the water heater itself the tank is corroded and water heater will need to be replaced.

If water is leaking from a pipe. then replace or repair the pipe or fitting. If the leak is coming from the unit itself, then replace the unit. Hope this helps.

Most likely only one of the pipes is leaking but weaping enough to cover the top and indented places near both inlet and outlet. This leak has most likely penetrated all the insulation and is a problem throughout the tank wrap insulation...If you are able to blow air continuously long enough to determine which connection is leaking then fix it. It will likely to take quite a while to dry out all the insulation if the water has migrated down into the tank wrap... If you determine that the insulation is waterlogged, you may be able to drill several small holes in the external cover.
good luck

could be pressure relife valve as well- you need to tell us where water is comig from exactly in order to solve
