YEah...I know what you mean...I almost got a pair from Pepboys. They are selling it at a crazy price compaired to the ones on Ebay. I remember I was trying to pick up some trim black-out tape to black out the trim around my windows but they ran out of them. That will probably be my next project after I get my suspension installed.

 

Butyl is that stuff that you see holding on the plastic sheeting behind your door panels. It's like a big string of licorice that has the texture and consistency of chewing gum. I get rolls of it from the expendable shops here in Hollywood. We use a ton of it on movie sets for all kinds of applications.

What makes the butyl good for resealing our lights is that it comes in either black or a light grey, the same color the dealer uses for seal them originally. It doesn't harden and provides for a great long-term sealant and it's easy to apply. Just unroll it and lay out the string along the channel then squeeze the housing together. No dry time needed.

In fact, that grey stuff that is originally used to seal the lights is some type of butyl. I have a roll in the garage. I'll post a pic of what it is in a few minutes.

 

Here is a link to mt car domain site where you can view the butyl. I'll do rolls for $20.00 shipped. They cost me $12.99 + tax per roll. I know it may be a little bit expensive, however, everything in the movie business is. You may be able to find it cheaper somewhere else. Good Luck, and contact me if you can't find it.
