You can use the Hempel Light Primer on all glass fibre, steel, aluminium and plywood boats. This light primer is for interior and exterior use, both above and below the waterline.

For uncoated surfaces below the waterline, it is recommended to apply 3 to 5 coats. For uncoated surfaces above the waterline, it is recommended to apply 2 coats. Surfaces that have been coated previously only need 1 undiluted coat.
