They never are as straight as one thinks when looking at what appears to be a pristine vehicle...use your hands to feel and especially your eyes to see...what you miss with these tools, guide coat and reflections will show where problem areas are. Find and object in the distance and watch for any distortion in the reflection because after you put shinny clear on the car that's what your going to see.
