I'm sure it has been discussed before,but humor me.during a recent outing i had a flat.my glue had dried up but luckily the town i was near had a shop. picked up some glueless patches for repair. i thought they were slicker than ... well you know. got me home allright but after several days i got another leak. seems the patch had rolled off and my prior repair failed. should i stick to glue ons??
