Ask any boatpainting professional and he'll tell you that you cannot 'work down' to a high quality finish - you have to 'work up' and that means care and attention to preparation of the surface prior to applying topcoats.
International's range of primers is designed to help you make this unseen but nevertheless vital area of maintenance as simple and efficient as possible. Care and attention in this area will maximise the performance of any topcoat and ultimately provide greater value for money in the longer term.
