Many years ago when tubeless had just come about, I went for a ride with RB member Smokes. He’d made a ghetto set-up consisting of latex mixed with various colour glitter. The idea being that the glitter would plug small holes.
When a large cut overwhelmed the latex he had to try and fit a tube in this snotty, glittery mess, he ended up covered in it which left him very sparkly! So, unless you want to look like Elton John when doing trail-side repairs, avoid this!
