Weatherstrip Installation Tips

General tips:

• If you notice bend or distortion of the weatherstrip due to packing, put the weatherstrip under the sun or in a hot car for a couple of hours to "unwind" the rubber back to shape
• Prep new weatherstrip that requires adhesive. Clean with denatured alcohol to remove mold release agent from the factory. See reference article.
• Where adhesive is required, use 3M Black Weatherstrip Adhesive on City Racer weatherstrips. Do not choose 3M "Super" Black adhesive, as it's not formulated for EPDM rubber.
• Caveat: Use 3M Super Black on OEM weatherstrips, as those are not EPDM. 
• How to properly glue weatherstrip

Windshield and glass weatherstrips:

• Installed without adhesive.
• Use the rope method. See reference video.

Door weatherstrips without pins (e.g. FJ40 front door and rear ambulance door weatherstrips)

• Installed with adhesive.
• Clean off old adhesive with 3M adhesive remover and/or Goo Gone.
• Install new weatherstrip with 3M Black Weatherstrip Adhesive.
• Fit FJ40 front door weatherstrips on the flat areas of the door periphery past the raised ridges. 

Weatherstrips with pins (e.g. FJ60 front and rear door weatherstrips)

• Installed without adhesive

Roof weatherstrip / seal

• Installed without adhesive

Windshield spacer

• The bolts holding the brackets  at the lower corners are multi-directional adjustment devices and should be loosened before installing the weatherstrip (All the bolts on the windshield frame are adjustable).
• Squash the seal by closing the windshield to its place gradually.
• The rubber is sandwiched between the seams of the mating panels at the front of the windshield to perform the sealing function.

Post installation

• It is normal for the vehicle's door to shut more tightly, or protrude slightly after installing new rubber. This phenomenon is widely observed with both OEM and aftermarket weatherstripping.
• After a period of time, the rubber will settle and become more compressed.
