We’ve had various brands of blacking over the years, none of which have been completely satisfactory but it is difficult to say why, or to blame the manufacturers. Preparation has a grest deal to play as has temperature and time to cure.
4 years ago I spoke to SML Paints and detailed our experiences with the various blackings. They recommended that, after pressure washing, to put on 2 full coats of Jotun Vinyguard primer plhs a further coat around the water line followed by 3 coats of SML Ballistic Black. I was quite impressed with the performance, especially the primer. Even on those high rub areas you could see the silver of the primer shining through where the black had been rubbed off. For our last blacking in May 2018 SML said just 1 coat of primer was necessary again followed by 3 of black. Of course, these extra coats require extra time in the drydock. In our case at no extra cost and you need to do it during the months when the water is warmer.
If money is no object then 2 pack epoxy is the way to go but whilst the coating may last much longer you will still need to drydock every 3 years or so to check all is well and touch up any scrapes.
Whatever you do, dont forget the bow thruster tube if fitted.
