Matman, I'm surprised your question hasn't brought up more responses!

I'll throw a little information into the mix to get things moving.

On the vintage Dodge vans I've worked on most of the door seals are held with small serrated plastic pins, but there are certain areas, like at the top of the rear cargo door seals, where what appears to have been a basic brownish contact adhesive such as DAP contact cement was often applied between the flat rear surface of the seals and doors, to improve the seal quality, in an effort to reduce leaks in that especially trouble prone area. When the old seals are peeled off, the adhesive often peels up a little despite it's age, so it must have been of pretty decent quality to remain flexible for so long. To my eyes, the adhesive appeared to have been applied via a small brush or buff applicator, rather than being sprayed on.

Many contact cements are intended to be applied thinly to both surfaces, allowed to dry till semi glossy, perhaps 15 minutes, then pressed together. This forms an aggressive bond.

Butyl Rubber cement is a very commonly used adhesive on automotive seals, such as on the windshield seals and roof vents. It's commonly pigmented black, and is available in small squeeze tubes and in caulking gun cartridges in many of the franchise auto parts stores. It cures pretty quickly, and remains flexible for extended periods of time, which is a great thing when attempting to install a flexible rubber seal!


I would tend to steer clear of any of the silicon sealer RTV type products or household types such as aquarium sealer or bathtub or window caulking. They may remain flexible for extended periods, and some can even tolerate ultraviolet and extended weather exposure, but they tend to shear badly in thicker flexed applications, and their cure time would make application on door seals a significantly larger headache than it needs to be.

I would definitely go over the area of the door to be adhered to with a quality degreaser, to remove any contaminants such as dirt, oils, waxes, or silicon. A light scuffing with a mild textured Scotchbrite scouring pad might even be desirable to improve the adhesion to the glossy painted surface of the doors.

From my personal experience, (-sigh...) I'd suggest that you may find it quite wise to apply a masking tape along the edge of where the seal will install, to prevent strings and drops of contact cement from dropping onto the cosmetic finish areas of the door. Contact cement typically contains some pretty aggressive solvents, which would definitely eat through the glossy surface of finish paint. Consider covering any nearby upholstery and the window glass too; it's unpleasant to clean off!

Thanks Ram.... yep, I`m surprised at the lack of response, thanks for your reply, I have just contacted the people who sold me the seals, asking if they can recommend what to use
cheers Matt

Get yourself a tube of windshield urethane sealant/adhesive. They will never come loose!

I've used 3M 08008 adhesive on many other projects and it works great although a bit messy. I plan on using it for my van seals too.
