Hi Nick,

Sorry i forgot to answer about the demonshine. I wouldn't advise using it myself on a Morgan. Would be fine to give a slight shine on an everyday car. The quality of the product isnt very good but it is cheap.... I think its a carplan product. Have a look at the link below for quick detailing sprays. A spray like these ones should be used repeatedly to enhance gloss and extend protection and should greatly enhance surface slickness, making washing and drying even easier and prolonging the life of underlying protective layers.

Hope this helps.
