The '82 Fuji Monterey I am restoring has a 1+ inch slit in the top of the vynl(?) seat. The material is a black textured leatherette type. Have used some dark textured tape but not happy with it. Any suggestions (other than using a different seat) for a really invisible job. Was thinking maybe I could mold the texture of the adjacent area and use some sort of RTV rubber to create a good blended repair. That seems too time and cost-heavy for the low budget approach I am taking to this bike.
