Leaking t-tops

[ianwells100]

my t-tops leak, just a bit, when it rains a lot (i live in vancouver, therefore it rains always), it leaks in about an inch behind the join of the t-tops to the car, on the windscreen side, and it leaks by allowing water to build up between the window and the rubber and it drips in slowly. my question is which product can help revive the rubber, i've heard mother's back to black and black magic work, but how well, also, i've heard baby oil works well,

that is one option, also, readjusting the door is another, would this work well and easily, and how would i do this

thanks
ian
