Shaving rear emblem holes...where to start?

what you need to do is get some spray foam and spray i little in the holes where the emblem was ,that will give the bondo somthing to hit .wait for it to harder and apply bondo,you DONT need alot of it the more you use the harder its going to be to sand it .then you need to sand it {ask a body shop about what grit to use } depending on the color of your car you might be able to use a spray can paint use only krylon dont get cheap paint .when it is dry i mean real dry wet sand it lightly till it is smooth then buff it out and your good to roll
