I've done some physical patches of sew-ups but I'm not especially good at it and I don't have much free time to do it anyway. Stan's Tire Seal works well enough for small leaks and is especially good because it works fast. On a commute it lets me keep going without spending 10 minutes installing a spare tire (or 20 minutes swapping/patching a clincher tube). When I've collected at least two sew-ups that didn't seal well with Stan's or that have sealed but won't hold much pressure without blowing out again, I'll send them to Tire Alert. My time is worth more than it costs to pay Tire Alert to fix them for me, and he does a FAR better job! I've got one Vittoria that I'm thinking of just pitching because the tread shows so many small cuts that it is probably vulnerable to more.
