[Christ]

I just went back through the list of mods to get here (I do this every so often, to keep them fresh in my mind... lest we forget...)

If you took those clips back off, and put some shrink wrap over the sections that touch the car's sheet metal, it would prevent any chance of galvanic corrosion, and help prevent the copper from wearing through the paint due to vibration. Plus, they'd have that much more of a friction coefficient against the sheet metal, which might promote an even better hold. And it would only take like 30 seconds per side.
