Just the blue residue to remove, is it best to wet and dry or use thinners to fully clean it off

Glad to see it worked for you.
I re-visited the residue, with even more brushed Interstrip and a cloth.
Eventually it all came off.

I have to say I have been really pleased with how the product worked and no damage to the hull.

Could pretty much polish it up, I heard of a case of a boat that was soda blasted and it took a bodyshop guy 3 days to polish the boat and even then it was mediocre, worth checking it out first.

I did the job on a 18ft sports boat once ,used a product called strippit from devon /cornwall if I remember rightly , that and a hot pressure washer ,worked fantastic , only trouble was the boat was antifouled by the boatyard from first delivery and they had roughed the surface with a disc sander to ensure good adhesion , I was starting with 200 grit ,then 500 then 1000 and 2000 . followed by g6 then g3 , I spent a whole winter at it , still got a bucket somewhere with every kind of sponge applicator and buffing wheel you could imagine not to mention remains of industrial packs of p1000 and p2000 , must confess I was well happy with the results which you could never tell it had been antifouled , I hope I never need that bucket again ha ha

Just need to polish the hull now

Finally got it all off, all in all used 4.5 litres of the Interstrip and many hours of swearing and stiff necks from lying underneath it, all I need to do now is get a polishing mop and some polish and get it back up to shine, hoping all of the blue that you can see will polish out.

As said before would have been quicker if the previous people had removed the barnacles first before anti fouling over the top.

Hoping to see some small improvement in speed and fuel consumption, the hull was really rough and bumpy before, now at least it is smooth

That's a really nice job - well done, I know what's involved

You will absolutely notice an improvement in speed. I would add the additional rider that weights play a big difference in top speed too. I sanded and carefully repainted AF on my previous RIB. At the same time I removed all her additional equipment prior to sale. That sort of gear would include tools, spares, many warps and spare anchor etc. It was quite a pile of stuff on the ground! I got about an extra 2 knots on a heavy 6.5m boat.

I see you're a glass half empty kinda guy...

Flip side is, had they given a damn, they would have also keyed the gelcoat with some 80 grit before painting - so maybe you lucked out!

Agreed, looks like they just gently buffed the hull prior to the anti-foul application, I was expecting worse but as I found the barnacles I started to get a warm feeling that the hull was in good fettle underneath and that the hull hadn't been keyed in as it could have been, as you can see from the pictures the hull is in good condition for what is a 2004 boat, the tube tapes also.
