I bought my mr2 and it did not leak in a light to moderate rain while driving down the highway. I left my mr2 parked outside at work during a down pour and my passenger seat was soaked. I tried adjusting the rings in the top and that did not work. The water was coming though where the front of the T-top met the front of the seal. I applied a few layers of tape like in the pictures and no leaks so far, which is great. I will update everyone to how the electrical tape holds up. I live in Indianapolis and it gets just as hot as it does cold so the tape will be put to the test. I might make a trip to a local vendor here in Indy that specializes in 3m products and see what they have. But for the cost of one roll of electrical tape its budget friendly
