I resprayed my 82' Honda 70 engine a perfect match from Halfords.Also buy at the same time a can of Active 8 # it is a grey etching primer for the alloy casings.Rub them down with wet and dry then wash in washing up liquid and water,rinse well and dry,Active 8 # is easy to apply and gives a superb finish,you need special primer for the paint to stick on alloy enginesGood luk.
