In the late 70s I went into a small auto parts place and purchased off the shelf a small bottle of "Tite Seal" gasket compound for automotive use. . I got home and was astonished to see on the directions that in addition to auto gasket application there were also directions for cementing bicycle tires. . The product was shellac. . I never used it on road tubulars, , I was concerned about the difficulty in getting the tire off. I was with a guy about that time and waited over thirty minutes for him to remove a flat tubulat that he had used some sort of contact cement on, I think his fingers must have been raw for awhile after that tire change.
