I have yet to do an X5 badge but the AMG ones I have done I usually give it 4 - 5 light coats and mask it off about a 1/4 inch away from the outside edge of the badge. I did my first badge using 2 coats and found the plastidip would not come out of the corners or peel smoothly. I also use a tooth pick to get into the tight spots or lift an edge. Hope that helps.
