Hi, those repair kits come with a metal sanding little surface which is to create a porous surface where the small hole was made. First you have to sand it down a bit.
(Hahaha... the connection played a trick on me and I hadn't seen the photo where you sanded it. I'm sorry for that) 🤣
Well... I hope it looks good and that no more air escapes. In the next few days I might make a video of this. I have one of my tubes with two holes in it, I fell into a pothole and it seems that the tube was badly mounted and the rim bit it.
I didn't fix it until today because I have 4 spare tubes.
I hope your bike doesn't realise that it was because it had a puncture that they washed it, because they like water and being stroked. I hope it doesn't puncture often.
jjjjajajjajaj I'm in big trouble then haha
🤣
