Went over to a friends house yesterday to pick up some parts he had found for me on his travels (no, the myth isn't that I have friends
)
In the parts was a Araya 7x with a badly perished comp3 copy, on removal of the tyre I found this.....
Yes, the plaster puncture repair myth does appear to work !! It was holding air when I picked it up
Now that's proper old school
