Buying Butyl Tape Locally
When I bought some butyl tape recently, I had a little trouble finding it here in the Metro D.C. area. I found auto shops don't carry it and glass shops don't carry it any more because they have started using something else. My local Ace and Lowe's hardware stores didn't have it either.
This is one of those cases where the telephone book and your telephone are your friends. I found a huge roll of 1/8" x 3/4" in grey for around $5.00 a roll at a local RV/marine parts place. You might want to check that sort of place first.
