On second leg of 825 NM flight; after a fuel stop; on IFR flight plan. Arrival airport AWOS was reporting 5;000 scattered; with a direct crosswind 11 gusting 15 KTS. Visibility was decreasing with dark clouds and airport in shadow. ATC held us at 3;000 FT until I saw the field and cancelled IFR. I was high but felt I could make the landing. Arriving over the runway the airplane floated in ground effect before touching down. I then realized that the runway was wet and could not get full braking action; and could not stop before running off the end into low overgrowth; sandy ground about 100 FT. No damage apparent and aircraft was pushed back onto runway.The late detection of the airport was a factor. I could have simplified the situation as I have done often in marginal or deteriorating conditions by requesting the ILS that I had dialed in but failed to use. I could have also done a 360 to lose altitude as I have done before. I should have considered the possibility of a wet runway based on the dark clouds in the area; but failed to register that until wheels were on the runway. I specifically rejected a go-around at that point because I had a full load of people and was not sure the airplane would climb before the runway ended and preferred a low speed overrun to a high speed crash. I do not often go into short fields and a lack of short field practice may have been another factor; though I was for some years based on just such an airport without any problems. Finally; the crosswind was another factor as I believe in using a higher approach speed in such conditions; which was not appropriate for this relatively short runway.
PA-46 pilot reported running off a wet runway when braking proved insufficient.
