Do these require any adhesive or fasteners to stay in place?

Installation method is not specified—test-fit before committing to adhesive or fasteners. Some buyers use trim-safe clips or contact cement; others rely on a tight friction fit. Start with a test fit to see what your handles need.

Will these fit over my existing door handle chrome or painted trim?

These are designed as direct slip-on covers for factory handles. If your handles have significant chrome trim or non-standard modifications, verify fit by comparing your handle profile to the product photos first.

Can I paint these or do they need any prep before install?

They ship in finished textured black—no sanding or primer required. If you want a different color, light scuffing with fine sandpaper before paint will help adhesion, but the covers are ready to use as-is out of the box.
