Front Plate Holes and Your Wrapped Bumper

A front licence plate comes off for a lot of reasons: the bracket is bent, the plate is cracked, or the car simply looks better without one. What almost always stays behind is the mount - two small threaded holes in the bumper cover - and those two holes are the part of the job most people forget to mention when they book a colour change wrap or paint protection film.

They matter because film behaves differently from paint. Paint has thickness and can take a screw; a wrap or PPF is a thin sheet with an adhesive backing, and a hole has to be cut out of it cleanly, with the edge sealed. Get that right and the holes are invisible. Get it wrong and they are the first place the finish fails.

What is actually left on the bumper

On most cars the plate sits on a bolt-on bracket, not on the bumper itself. The bracket uses two threaded holes, usually on the upper or lower half of the bumper face, and the plate is held against it. Behind the cover there is usually a metal reinforcement panel inside the bumper cavity.

Three states are worth knowing before the car comes in. The plate and bracket are on and staying. The plate is off but the bracket is still bolted on, which is the state most cars are in. Or both are off, leaving two open holes in the plastic. Which one you are in decides how much work the bumper needs.

Why the holes are harder under film than under paint

With paint, a hole can sit for years and collect a little grit. With film, the hole is the weak point.

• If the film is stretched across the hole instead of being cut around it, the hole reappears as a tear the first time the car is washed, and the edge around it lifts.
• A cut-out needs a narrow border of film folded back and sealed, and that seal is what keeps road salt and grit out of the cavity behind the bumper.
• On PPF the same cut-out is made in a separate piece, and an unsealed edge around a hole is where film edges start to lift.
• The tow hook on a set of aero parts is the other cut-out on the same bumper, and the two are usually handled in the same pass.

None of this is difficult work, but it is work that has to be asked for. If the plate is coming off and nobody mentions the holes, the holes get dealt with after the fact, in a different session, at a different cost. A winter wash will not clear grit out of an open hole on its own, and the grit stays against the bare metal behind the bumper.

The order of work matters

If the plate and bracket come off before the car is wrapped, the bumper goes into the bay with clean, empty holes and the film is cut once, properly, with the edges sealed. If the plate comes off afterwards, the same cut has to be made in finished film. That takes longer, it leaves a cut line in a place you look at every day, and the bumper comes off the car twice.

There is also the question of what goes in the hole. Keeping the bracket on keeps the plate mount available for a dealer plate or a later sale. Filling the holes with a bonded trim piece gives a cleaner bumper but closes the option of putting the plate back. Both are normal choices, and both belong on the quote rather than in a decision made in the parking lot.

What to ask for when you book

• Tell the shop before the work starts whether the front plate is staying on, coming off with the bracket, or coming off and leaving the holes.
• Ask what happens to the mounting holes in the film or the protection film, and get it in writing on the quote.
• Ask how the edges around the cut-outs are sealed, and what gets done about the salt and grit that ends up in an open hole over a Vancouver winter.
• If a tow hook is on the same bumper, ask how that mount is handled.

Most of the cost of a wrap is in the panels, not in the cut-outs, but the cut-outs are where a finish shows its quality. Get them specified before the film is ordered, take the plate off in the bay rather than in the parking lot, and ask a shop that installs both protection film and wrap to quote the bumper either way. You can see what each option covers on our colour change page and our paint protection film page, or ask us to detail the car first so the bumper is clean before the film is laid.
