Headlight seal adhesive

The 3M stuff is really easy to find also, but it does have the nickname, "gorilla snot" (for the yellow) for a reason.

Reminds me of an old joke:
Ya know why gorilla's have such big nostrils?

Cause they have such big fingers!

I used the two sided tape that you can find at HD. It is used for attaching those heat-shrink plastics to the inside of your homes' window frames (for us renters). It's super tacky, and very thin. It comes in a .375" width and is super easy to work with. Just clean the headlight with alcohol before sticking it on. No mess after that.

Good idea on the tape. What you are talking about is or should be an adhesive transfer tape. 3M makes 2 that would be very well suited for that application. One is 3M #950 and the other is 3M #926. Both are 5 mils thick and transparent. The 950 has 75 OZ per inch width of adhesion and the 926 has 150 oz of adhesion per inch width. The 926 would obviously be the better choice. Clean around the headlight with any good solvent that will not attack the polycarbonite headlight plastic (very improtant to avoid crazing or hazing.) Clean the gasket of any residual adhesive. Apply the tape to the gasket, use adequate pressure to insure a good bond to the gasket. Remove the liner and stick the gasket to the headlight applying the tape with good pressure. Happy motoring without the flapping.
