The pilot stated that he initially touched down in the first 300 feet of the available runway, but bounced twice. The pilot further stated, I didnt like the landing and decided to go around. The pilot reported that after the second bounce, and while still airborne, he added full power, …but nothing happened. There was no acceleration. The pilot related that the airplane subsequently settled back on the runway before sliding off the right side and impacting a taxiway sign with the inboard section of the left wing.Reported weather at SUN included wind velocity of 270 degrees at 8 knots.
