If your area has a Tech route salesman, everything you need
is on his truck:

Interesting.
Thank you for that reference.
That site has a lot of details for each fluid.

They have vulcanizing fluids and cements for example:

However, the vulcanizing cement is easy to come by; but the black
goopy final inner liner sealer (tar?) is the hardest to find on the street.

I think this is that sealer (Butyl Liner Repair Sealer):
http://www.techtirerepairs.com/produ...ments/739.html

It's made by Tech International, 200 E. Coshocton St., Johnstown, Ohio 43031,
740-967-9015, and also listed by Chemtrec 1-800-424-9300. So I will call
them tomorrow to ask where I can get small quantities and what is a suitable
substitute.

The ingredients on the MSDS don't tell me much:
50 to 100% solvent naphtha (petroleum blend), light

Does anyone on this newsgroup know of any commonly available substitute
for this black goopy inner liner sealer?
