Bicycle hose mending in seconds - with seconds glue
After finding the hole, release the air. Then a little "blob" super glue (no gel) on the hole.
Now quickly with your thumb a plastic bag for 1-2 minutes firmly press on the spot (attention, will be warm). The superglue hardens now, but does not connect to the plastic bag. What remains is a clear film that closes the hole forever.
Is not good for high PVC content in cheap hoses. But no other glue will help.
