Re: Seal a flat? I've had plenty of punctures repaired on race tires, but they've been mainly for autocrossing, which is almost always under 60 MPH. If you're talking about speeds that may stay above 100 MPH for a period of time, I'd make sure the mechanic really knows what he's doing and uses a patch from the inside of the tire. Even then, I'd think long and hard about whether you'd not rather just have a new tire. You're asking a race tire to do a lot of things a normal street tire can never do, and that patch is designed for street tires.

Re: Seal a flat? Was the hole patched? I have had Nitto DR's patched before and raced. Took the car to 160 on a patched tire.

Re: Seal a flat? I've always used plugs. I've never felt safe with patches and can't seem to find anyone that can do one that doesn't start leaking again anyway.
I use the brown plugs not the black ones. The brown ones seem alot more pliable and I use plenty of cement glue. Ream out the hole (yeah baby!) apply rubber cement, ream some more (aah yeah), apply more rubber cement, and plug the hole (uhuh) then trim the plug.
I terrorize my tires and I've never had one fail because of a plug. Plenty of 100mph+ sprints.
The only time I'd be leary is if the hole's on the shoulder where it starts curving up.

I don't think the plug could do much more damage than the object that made the hole though. Your ideas?
