Seeing myself resembling the Monty Python 'Its' character waist deep in used sandpaper wasn't really an option as
a) i'm impatient by nature and
b) i'm working all next week , so i need to get a lick on.
For some reason the sandblaster wasn't upto the task, in return for removing a piece of non-slip no bigger than my hand it duly emptied 25kg of sand all over the foredeck......... sod that, my breathings only just got back to normal from stripping the hull.
Time for a re-think, so after much surfing i concluded either a grinding cup or a ferociously abrasive pad both of which attach to my 4" grinder. Having returned from purchasing said items it was time to try them both, first up the grinding cup which essentially is a diamond cutter you can use in a grinder.
This 'ploughed' through the non-slip..........and also a significant part of the cabin roof, next it was the turn of a 20 grit abrasive disc. This proved just as 'efficient' at destroying the cabin top but was eminently more controllable.
As you can see from the pictures (like me in 'speedos') it is not pretty but weighing up how long it would take to sand the non-slip off i feel it will be less time consuming to cut all the paint from the cabin top and decks then fill and fair with 404 / 407 fillers.
Of course I could live to regret this decision.
