I definitely recommend fusion tape (I've heard some electricians call
it "rubber tape"). I had the exact same problems with my laptop AC
adapter plug. I basically "rubberized" the plug and 2-3" of the cord.
Not a single problem since. You can find it with the electrical tape
at most building supply places that carry electrical things. The key
to making it work is to stretch it as you apply it. It's really handy
for all kinds of electrical repairs, and is actually completely
waterproof, unlike regular vinyl electrical tape.
