Mirror Cap Overlay Installation Guide

Mirror cap overlay being placed over a Toyota Tacoma side mirror

Mirror cap overlays fit over your factory mirror caps. They do not replace the mirror or the cap. Each overlay is held on with pre-applied 3M automotive acrylic foam tape and is made to fit your truck without any modification to the mirror.

Before you peel anything: do a dry fit. Once the red backing is off the tape, the part is considered used.

What you will need

  • In the box: left and right mirror overlays with tape pre-applied and an alcohol prep wipe. Some sets also include strips of blackout tape.
  • Isopropyl rubbing alcohol and a clean, lint-free white cloth. A 3M prep solvent also works if you have it.
  • A hair dryer if the mirror is cold. The surface should be 68 to 100 F (20 to 38 C), and never below 60 F (15 C).

Prepare the mirror cap

  • Make sure the factory mirror cap is clean, dry and free of debris. Remove oil and grease with a cleaner first, then wipe the areas where the tape will stick with isopropyl alcohol and a clean cloth. Do not use shop rags.

Install

  1. Dry fit. Go through the installation steps below without removing the red backing, to check the fit and get a feel for the movement.
  2. Clean the areas where the tape will stick once more with the included alcohol wipe (or a 3M prep solvent).
  3. If blackout tape is included, apply it along the lower edge of the factory mirror cap so no chrome can show through at that edge.
  4. Peel the red backing off the double-sided tape on the back of the overlay.
  5. Gently pull the edges of the overlay outward to widen its opening, so the tape is less likely to touch down early.
  6. Hold the overlay with the top edge tilted toward you, so that only the bottom edge meets the factory mirror cap.
  7. Slowly tip the top edge back toward the mirror, keeping the bottom edge covering all of the original cap.
  8. Check around the edges to make sure no chrome shows. Shift the overlay if needed. Once you are happy with the fit, press firmly on all taped areas.
  9. Repeat on the other mirror.

After installation

  • Press all taped areas again after a few hours or the next day.
  • Wait at least 24 hours before washing the truck.
  • The tape reaches full strength after 3 to 5 days at temperatures above 70 F, and longer in the cold. Once bonded, the overlay is very hard to remove without damaging it.

Care

  • Treat the overlay like a fine paint finish and use good quality car care products.
  • Gloss: light scratches can often be buffed out.
  • Matte: abrasion leaves a permanent glossy sheen. Do not buff it, and use a brushless car wash.
