Umm... is it leaking right where the plastic and medal clip together at the top of the radiator? That prollyt means the plastic core cracked and you should get a new radiator.

OE Honda ones will cost you an arm and a leg. Unless you do some high-end racing, a cheapo aftermarket radiator from www.radiators.com will suit you fine. I got one installed within 6 hours of calling them for about $200 including labor. Not bad, and I could have done it cheaper myself, but replacing the radiator can be really messy, especially in a car port at an apartment complex...
