Another Trunk Seal Thread...

I've searched and understand about getting the channel nice and clean and perhaps using some rust converter if needed (it is needed), and maybe some 3M gasket seal.

Anyway, what I'm not clear on is whether I have the seal oriented properly. Does the concave side of the rubber ring go inside while the more convex side is oriented outward? I haven't glued it at this point, but it seems to fit best this way.

After fitting in the not-yet-glued seal, I have maybe 2 inches or excess. Would I actually cut/trim the seal, say at some strategic point for "fit" ?

Muchas gracias ,

Chuck

No, no, don't cut it. Did you accidentally "stretch" it while putting it in the channel? That would leave you with excess...

As for oreintation, the "tall" side of the seal goes toward the trunk entrance....... That way water running in throught the crack between the trunk lid and car body will puddle in the little channel in the rubber seal and run downhill out of the car.

Mine have the convex side in, "cupping" outward.

if you look at the seal as a cross section, you will notice it has a large round part, and a thin flap. the flap portion of the seal goes up on the inside of the trunk as opposed to putting it on the outside of the circle the trunk opening makes. .. if I was in the SD today, I would take a picture for you. the seal should have a large channel on the outside of the circle for water to collect in, with the flap pointing up toward the decklid to keep water out of the compartment.

Thanks all for the orientation info! I'll check it out this weekend. I guess the biggest concern is the 2+ inches of "slack" that I seem to have, otherwise it seems to fit pretty well with the convex side cupping inward as 1983/CD reports. Or at least I think I understand. At least on my set up, it seemed to fit best where the convex side was not the exposed side. (?).

Did I mention what a great resource this is? Folks are just great on this forum and I try and help out as I can -- NOOB that I am!

on the extra you seem to have, just pull it back out, and as you are putting it back in, don't stretch it at all, just push it in, if you still have extra, try pushing it together up top and around the bottom.

I'm currently replacing my trunk seal, and like a noob I don't remember which way it goes back in. Try as I might, I just can't figure out how it goes in even with these descriptions. Could someone either post a good picture of an SD seal intact or try to explain how it goes in?

Specifically, the long side with the tall flap, back / front / inside / outside ...none of those are clear to me. Does the tall flap side go closer to the windshield or closer to the bumper?

Thanks!
