Can't remember exactly the name on the bottle, its on the boat but made by International, got it at our local chandlery. Yes did use a polisher on some of it and elbow grease on the rest.
She is new but was covered in grime from being alongside the quay wall for six weeks. The hull looked like someone had gone over it with wet and dry as the fenders had picked up grit off the wall and scuffed up the gelcoat quite rotten. Anyway she looks like new again and looks hunky dory.
My father, he has an apartmet overlooking Douglas Bay right on the edge of King Edward Road which is about 20 yrds from the slope down to the bay.
We took a whizz past whilst he gave me instructions on the mobile, left a bit, right abit, come back again, turn around, oh sorry left the lens cap on etc etc. Took some video as well which looks brill, never realised how 'throaty' the engines sound from the shore but I guess you are leaving the sound behind you as you hurtle along. Sounds the dogs doofers though.
