In case of using your patch kit, you’ve located
where your hole is, let’s say it’s right next door to this seam and it’s a puncture from
glass so it’s small, you can use the smaller of the patches, the smaller is the better.
This seam has to go away so you utilize the sandpaper to make this seam go because the
edges of the patch can’t be lifted over the seam. If it does air is just going to leak
out from the puncture, past the seam and the patch will not be effective. This may take
some time to prepare so be patient,
don’t be afraid to sand more area than you need. Check this against the size of this patch,
it seems like we’ve got most of the seam away from where it would go past the edges, this
orange feathered edge is what you want to have seated nicely against the tube.
