First, i'll admit that I am not a C6 export or an AC expert.
But here is what I know:
1) You want to plug the leak as soon as possible. With an open hole, you can get moisture inside the AC system. This can damage other parts of the system.
2) if you decide to repair instead of replace, you need to be careful. The condenser coil is on the high pressure side (I believe, correct me if I'm wrong). This usually has several hundred PSI of pressure in it (250-300 psi is pretty normal). This means that you will need a patch that can stand up to that kind of pressure.
3) After you patch it, you need to pull a vacuum on the system in order to bleed out any moisture that got in. Most places leave the vacuum on for 15 minutes, but I would let the car sit for as long as possible (I have let my cars sit overnight).
4) I would fix it before it gets too warm outside.
Honestly, I would replace the condenser coil if there was room in the budget. If not, i would go to an AC shop so that I got a patch that would hold.
Good Luck!
