This type of glue is known as contact cement, for it sticks to things it makes
contact with, and even better to itself. If your car or truck has been around
long enough for a few presidents to come and go, or gets an unusual amount of
sun, this glue can lose contact with the weather strip. Once the glue fails,
the weather strip comes loose and newfound whistling and noise can make its
way into the relative quiet of your cabin. Worse is that water can also make
its way in. Rotten carpet, musty odors, and a rusty floor pan are right around
the corner. Loose weather strip is also prone to getting pinched in the door
and shearing. The fix is simple.
|Step 1 - Here's the problem. The glue has simply given up after 20-plus
years in the warm California sun.
|Step 2 - Clean and dry the weather strip and mounting surface with some
Naphtha. Test fit the weather strip before applying adhesive.
|Step 3 - Weather strip adhesive and contact cement is nasty stuff. Wear
gloves, eye protection and disposable clothing. Do not breathe fumes. Use a
rag to keep excess off painted surfaces.
|Step 4 - Apply a thin layer of adhesive to both surfaces. Allow the
adhesive to dry.
|Step 5 - Align the weather strip and press firmly into place.
|Step 6 - Clean up any excess adhesive. If noise or leakage problems
persist, the weather strip may be overdue for replacement.
