when i've gotten cuts in the casing i'll use the dollar bill trick to finish out my ride. you can also use Fedex Tyvek envelope, folded over a few times, and large enough to generously extend beyond the cut.

when i get home i cut out a piece of casing from an old tire, larger than the size of the gash. super glue that on the inside of the tire, and then super glue a piece of tyvek paper over the casing patch. just for added reinforcement.

done this many times. and ridden hundreds of miles on tires with this repair without incident.

Anything through the casing and I just cut 2-4 pieces of duct tape depending on the size of the cut and use those. Clean the inside of the tire really well and they will stay for a long time.

Ancient thread but a heads up. Can almost be used like a filler, leave proud, go for ride. Filled a cut where I could see my patch on a GP5000 and has blended nicely. Tubed obviuosly.

I should add that for a tyres as thin as a gp5000 the included emery paper should not be used on the inside of the tyre as you'll blow straight through the cords. Contrary to popular belief, roughening the tube doesn't promote adhesion per se; rather the fact that you've removed mold release from tyre's manufacture. I use a silica sponge.

I have never bothered with this but I have done a lot of bonding of plastics and rubbers. I’ve learned a number of things:

1. Not all ‘superglues’ are created equal. In fact, most suck at bonding anything but the most easily glued plastic.

2. If a fast curing and high strength bond is the goal, and rubber is the substrate, you can do no better than Loctite 401, primed with SF770. The resulting bond will be stronger than the rubber and it cures nearly instantly. Be sure not to get any on your fingers!
