Method of manufacturing aluminium alloy rolled sheet product with excellent formability and good paint bake hardenability, including: casting Al&#x2014;Si&#x2014;Mg aluminium alloy ingot including, in wt. %: Si 1.0% to 1.50%, Mg 0.10% to 0.40%; heating the ingot to above 550&#xb0; C.; maintaining the ingot above 550&#xb0; C. for at least about 4 hours; cooling the ingot to 460&#xb0; C. to 520&#xb0; C. Maintaining the ingot at 460&#xb0; C. to 520&#xb0; C. for less than 6 hours. Hot-rolling the ingot in one or more rolling steps to intermediate gauge of 15 to 40 mm. The hot-mill exit temperature is 370&#xb0; C. to 480&#xb0; C. Further hot-rolling from intermediate gauge in one or more rolling steps to final hot rolling gauge. The hot-mill exit temperature is 310&#xb0; C. to 400&#xb0; C. Cooling the hot-rolled material at hot rolling final gauge from hot-mill exit temperature to ambient temperature. Cold rolling the hot-rolled product to a cold-rolled product of final gauge.
