Sanding should be done on the same day. Applied on sheet metal, galvanized and old painted surfaces to give a smooth appearance to topcoats that will be applied later (synthetic ones must have been applied at least 3 months ago). It is a primer with high filling power and suitable for sanding on the same day. Excellent stock stability.
