99' V6 A/C leak

I bought a 99' v6 5 speed recently that has a number of problems. Of of them is the A/C has a slow leak. I tested this by vacuuming the system. After 15 minutes I had lost ~15 inchs of vacuum(I think that's what the gauge measurement was). I was wondering if there's common trouble spots on this car that I should start my search with to find the leak.

I don't have access to the special flashlight and glasses needed to see the special dye. It's a slow leak so I think charging the system might be a waste of time as I probably won't be able to see an obvious leak.

Thanks.

Look for a darker area on the condensor, wet or oily lines (especially at the junction between hard and soft lines), oily area between the compressor and pulley on the bottom side. These are the common leak spots on most cars

BTW 15" of vacuum in 15 minutes is a large leak, your refrigerant would be gone within an hour if you recharged it.

Oh, I'm used to large obvious leaks in my short experience with A/C. I usually deal with farm machinery and it's easy to spot problems, usually a line breaks or get's bent and kinks, easy stuff to find.

Most auto parts stores sell a dye kit with a infrared flashlight for around $20.
