Will this mirror work on my truck and car both?

Yes. Universal mounting bracket works across most vehicles with standard mirror posts or door mounts. You may need different fasteners depending on your vehicle's existing mount points—test-fit first before drilling or using adhesive.

Does the convex glass reduce image quality or distort what I'm seeing?

Convex glass naturally magnifies and widens your view, so objects appear slightly smaller and farther away than they actually are. This trade-off is exactly why it kills blind spots—you see more area, not less. Takes about five minutes to adjust.

Do I need to paint or prep this before installing?

The black housing comes finished and ready to mount. No prep needed unless you want to match a different color—in that case, clean the surface and use automotive paint rated for plastic or composite materials.
