O.K. you guys....I washed my Mach today with a pressure nozzle intent on seeing if the sealing strips from CJ's Pony Parts did the trick. The results are a resounding success. Just as it should be. Now, I must admit, there was no mention on the internet about sealing the raingutter piece to the roof first....that was just my take on it, as there are four screws going into the body, and I wanted to be sure they didn't seep, or leak OVER the roof-rail weatherstrip channel. Then, I attached the self adhesive foam strip to the bright metal weatherstrip channel piece(s), and attached that up to the roof. This all seemed fairly straightforward to me and I don't see why any of you shouldn't get the same results.
Another upshot to this is, that It's about time to replace my seat upholstery ( again ). As long as the rear seat back and bottom are out ( removed because you need to remove the rear side panels and rear glass to do the seal-up job ), and my beautiful wife got me an entire seat upholstery kit last Christmas, now is a good time 'cause the rear seat is out. The seats are in the upholstery shop as we speak, and I'm driving around with just the driver's seat in. When the seats already in the shop are done ( this week ), I'll swap out the driver's seat and have it done last. The two front seats are interchangeable. This will be the third time the seats have been upholstered, once from the factory, and now twice since as long as I've owned it. Like I have told people....I drive this car everyday and wear and tear is a part of useage but I keep it maintained as well.
