Apply using a clean, good quality brush. Apply a thick even coat of paint taking care not to spread it too far. Failure to do so may require a second coat, particularly when painting over a darker colour with a lighter topcoat. Leave a minimum of 16 hours between coats. Whilst leading edge technology has been used in the development of this product, the nature of solvent based paints means that they will discolour over time. The rate of discolouration is faster in areas with low natural or UV light.
