They probably all use the same company for their weather stripping. I heard the company Paul uses is real good as well
No actually we do not. I have went thru a lot of weather stripping. I have purchased seals from about every gbody seal manufacturer out there. When GM went crazy I knew we had to find an alternative. Alot of our seals are GM licensed. I just spent a better part of my evening & still working on a Moon roof pan seal. I have a new aftermarket piece, an original un installed GM unit, & a good used low mileage one. As bad as we need to get this seal approved I haven't yet. I will be here for at least another 2 hours measuring, fitting, installing, & making notes on the proto type to send back.
I have the glass moon roof / astro roof seal approved.
I spent hours reading feed back on people who installed new GN seals on cars in the last few years. I figured out that the original would grab against the glass. We made ours a little smoother to allow the glass to slide against the seal not grab it & bind. This makes for a tight level seal with more coverage from glass to seal.
We don't send seals out for our customers to test we test fit. We test fit on a bunch of different vehicles we own. We send seals to Mike at Richard Clark's place if we feel we need a second opinion. Kirban now carries our t-top seals.
I am also working on getting the wire installed back into our hard top seals. They fit fine now but would be 100% dead on with a wire to GM's originals.
If you get bored look at all the work we just did to build new GM style bumper fillers that are better & will last longer then the originals.
We hate returns due to some one being unhappy & we use what we sell. although we offer a $ back guarantee if your not happy after dry fitting it.
Thanks for the positive feed back on the seals you have bought from us. It makes all the time doing test fits worth it.
