Product Description
Mercedes GLB 2020-2026 Stainless Fuel Door Accent (GC70985)
GC70985 brings a polished stainless face to the fuel door of the Mercedes GLB, a 4-door SUV, across model years 2020 through 2026. All seven years sit on one Fitment row, so there's no split by year to sort out. It's a single piece of 304 stainless steel at 26 gauge, made in the USA, and it ships with 3M automotive-grade acrylic foam tape.
It is not a replacement cap and not a replacement part. You MUST have the existing gas door to install this piece. What you're buying is an overlay that bonds to the GLB's own door, not a new door.
Paint first. QAA states the tape will hold for a lifetime without causing any damage to the surface of the vehicle, and the tape's grip is only as good as the finish under it. Run a fingertip around the door edge and look across the face in good light. Fix chips, flaking or milky clear coat and any blisters before you start, and confirm the door sits flush when closed.
No tools to speak of. There's no drilling; the trim installs directly over the existing surface. What you need is soapy water, a clean towel, a degreaser and a roll of painter's tape. Wash and rinse the door, dry it fully, and degrease it so the tape meets bare paint rather than wax.
Line it up before it sticks. Keep the liner on and rest the trim on the closed door. Shift it until the paint showing around the stainless is even on every edge, and put a strip of painter's tape at two corners as guides. Then peel the liner, set the piece against the guides, and press it down firmly across its whole surface. A second round of pressure a minute later helps the foam seat. Open the door slowly once to make sure it doesn't catch. The Installation tab walks through the same process.
The rest of the GLB list. Five parts are cross-listed, all for the 4-door SUV. Pillar post trim comes in three sizes: PP70985 with four pieces, PP70986 with six and PP70987 with eight. The sheet doesn't describe what the larger GLB sets include, so compare the photos. RW70985 is a two-piece set of rear window side accents, and RD70985 is a one-piece rear deck accent with a width of 0.75 inches. Together with the gas door trim, those cover the side glass and the back of the vehicle.
Living with it. Polished 304 stainless has a bright, mirror-like finish, and the 26 gauge sheet keeps the profile slim against the door. Install on a dry, mild day and give the tape a night to set before washing. After that, a soft cloth and mild soap are all it takes, plus a quick wipe if fuel drips on it.

Installation tips: Gas Door Cover Trim
- Confirm your vehicle still has its original gas door. This trim mounts over it and does not replace it.
- Unpack the piece and hold it in position to confirm the fit before mounting it.
- Each piece mounts with 3M automotive-grade acrylic foam tape, so clean and dry the mounting surface first; the tape needs paint or trim free of dirt and wax.
- Align the piece and press it firmly into place directly over the existing surface, working along its full length so the tape bonds evenly.
- Step back and check alignment before pressing along the full length of the piece.
These are general tips. Follow any instructions packed with your kit if they differ.
