Thanks very much for all your replies, clearly the consensus is that it's best to prep the steel properly by removing all the Mill Scale. (Pretty much as I expected). My present boat (Dutch Steel Motor Cruiser) has two pack (Awlgrip) throughout, and it gets lifted every 2 or 3 years for Antifoul only. The paint above and below the waterline has never needed any attention in 17 years. I am beginning to realise that there is a massive difference tween the high volume yards and the smaller builders in terms of quality, but demand is such that the volume yards dominate and surprisingly even demand high resale values. I guess this comes down to the fact that if it floats, why worry.

Hello I'm looking to have a new boat built, but am surprised by the number of builders who leave Mill Scale on and paint over it albeit with two pack. What is the general consensus of opinion on this question, am I being too fussy wanting the scale removed ? Thanks
