Most installers stay with a film supplier long after it stopped making sense, and the reason is almost never loyalty. It’s that switching feels like it will cost a week of production, and nobody has a spare week.
It doesn’t have to. Switching PPF suppliers is a logistics problem with a fairly boring solution. Here’s the sequence that works.
Before you switch: get honest about why
Write down the actual reason. It’s usually one of these:
- Lead times are costing you jobs.
- Margin is too thin at their pricing.
- You’re getting quality complaints — yellowing, edge lift, staining — and eating the redos.
- They approved three more shops in your area.
- The colour range is too narrow to sell the work you want to sell.
This matters because it tells you what to test for. If you’re leaving over lead times, price is not your evaluation criterion — stock depth is. If you’re leaving over yellowing, you need to interrogate the material, not the invoice.
Step 1: Get film in your hands before anything else
Never switch on a spec sheet. Order a sample and test it the way you actually work:
- Stretch it around a real compound curve. A bumper corner or a mirror cap tells you more than any datasheet. Watch for stress marks and how much heat it needs to relax.
- Check clarity over dark paint in direct sun. Orange peel and haze hide indoors under shop lighting and appear the moment the customer parks outside.
- Test the self-healing claim. Put a light scratch in it, apply heat, and see whether it actually disappears.
- Check tack and repositionability. How forgiving the adhesive is directly changes your install time.
- Leave a piece somewhere sunny for a few weeks. Not a lab test, but it will tell you something.
Do this with the specific films you actually run — including a colour if colour work is part of your business. Clear gloss performing well tells you nothing about how their satin behaves.
Step 2: Confirm the commercial terms in writing
Before you move volume, get clear answers on:
- What the opening order requires, and whether you can reorder single rolls afterwards.
- Whether a paid certification course is required before you can buy at all.
- Which SKUs are stocked domestically and typical ship time.
- Warranty length, what voids it, and who administers a claim.
- Territory policy.
- Roll width — 60 inches is the practical standard, and anything narrower will cost you in seams and labour.
Our wholesale pricing guide covers how to compare these on a cost-per-vehicle basis rather than cost-per-roll, which is where most comparisons go wrong.
Step 3: Sort out your existing warranty obligations
This is the step people skip and regret.
Film you have already installed carries warranty obligations that don’t disappear when you stop buying from that manufacturer. Before you cut ties, find out:
- Whether existing customer warranties remain valid after you close your account.
- Who handles those claims going forward, and how you contact them.
- Whether you need to keep any documentation, batch numbers or registration records.
Then keep a record of every vehicle you’ve done under the old brand. If a claim shows up in eighteen months, you want to know which film is on that car without guessing.
Step 4: Run both brands in parallel for a short period
Don’t cut over cold. Order your opening inventory from the new supplier while you still have stock of the old, and run the new film on lower-risk jobs first — your own vehicle, a staff car, a repeat customer who knows you and would forgive a hiccup.
Give your installers a few vehicles to adjust. Every film has slightly different stretch behaviour, heat response and tack. The learning curve is real but short, and it’s far cheaper to climb it on a friendly car than on a customer’s new build.
Step 5: Update everything that mentions the old brand
Easy to forget, embarrassing when a customer catches it:
- Your website, service pages and pricing sheets.
- Quote and invoice templates that name the film brand.
- Warranty paperwork you hand customers.
- Shop signage, window decals and vehicle wraps.
- Google Business Profile description and photos.
- Any directory listing where you’re listed as an authorised installer for the old brand.
Step 6: Tell your customers something useful
You don’t need to announce a breakup. But if you’ve switched to a film with a wider colour range, better self-healing or a longer warranty, that is a genuine reason for a past customer to come back — and it costs you nothing to say so.
Existing customers who already trust your work are the cheapest source of new jobs you will ever have. A supplier change is a legitimate excuse to talk to them again.
How long it actually takes
Realistically: a week or two of sample testing, a day of paperwork, and a handful of vehicles to get comfortable. The part that takes longest is deciding — not doing.
