I did use some of the plastic variety hand clamps on the tips just to make sure it adhered well in those areas

BMW includes the tape with it, maybe it is of the right thickness? I bought a used spoiler and got the 3M tape from autozone, however on the front edges the tape just sinks and there isn't enough bulge for it to touch the trunk.
