How do I two tone with shaved drip rails

[SS Tim]

Might try working the end down to a rounded or spear tip. Or even a flat roll then blending to shape. If there is not enough metal to do that consider buying the bulk trim from a trimmer that uses it for vinyl top work. It clips on the same way and is soft aluminum. A painted pinstripe would work to separate but you have holes already correct?

Edit This is the problem as I read it.
