I've found this spray paint easy to use and gives a good finish but there was always one drawback. It always said on the tin, if you don't get all coats on within a couple of hours you have to leave it 6 weeks to fully cure before adding extra coats. Invariably you would miss a bit somewhere and be unable to rectify it. I'm just using a tin of the silver spray on a motorbike wheel hub and the instructions don't mention this 6 week business. Does anyone know if they have changed the formulation of this paint?
