Meguiars plastic polish will help with those swirls. Meguiars #26 also works pretty well for protecting things from light scratches once you get things cleaned up. If that doesn't work there are other options but always try the least invasive first. The dark wood from say...the 92/93 400Es shows every little thing. The Zebrano and the lighter burl walnut show a bit less. Be very careful, since it swirls that easily it is also easy to take the finish off so be VERY gentle/careful. If that doesn't work post back and we will take it from there. BTW, what model do you have....hence what wood scheme do you have?
