possible coolant leak

[wvboxst3r]

I have noticed a slight smell of coolant since I purchased boxster at Christmas. Yesterday I noticed a wet look inside fenders. Looked the best that I could under car and noticed a little fluid on brace infront of muffler.

I then checked the coolant level and it was just barely under the min level.

Some quick background. The dealer had the coolant hoses replaced and some seals. I have put over 2k miles on car with some spirited short trips and two 500 mile trips. Temp gauge stays around 180 when I am moving and will go to about 190ish when idling.

I added enough water to bring to under max about 12ounces.

Any ideas?
