There are several methods which depend on the challenges involved.
1. If it's an area that will not have thick bedliner material around it, simply use masking tape. However, you may need to use a razor blade to cut the bedliner material if it gets thick is a spot. Careful not to end up with masking tape underneath the bediner's edge, it will be very difficult to remove it!
2. If possible, we use a wire tape. We can mask, spray, and then pull the wire to produce a perfect edge.
3. Remove the emblem, apply the bedliner, glue the emblem on the bedliner material with "3M Emblem Adhesive".
I believe it's just plastic.
