Do these require any adhesive or fasteners to install?

Mounting method isn't confirmed in the product specs. Before committing to adhesive, test-fit the covers to verify they sit flush against your factory handles — you may find they clip or snap in place without additional fastening.

Will the chrome finish hold up to car washes and sunlight?

Chrome-plated ABS is designed to resist UV fading and weather exposure. Over time, any chrome surface can show wear, but quality plating on ABS holds its finish longer than bare plastic.

What if one of the covers cracks or the chrome peels?
