For manufacturers and distributors

How your film behaves in a real shop.

Lab data tells you what a film does on glass. I can tell you what happens between the box and the car: on the plotter, under the squeegee and in the customer's driveway a month later.

Nearly four decades installing, selling and running tint businesses. Publisher of the Film Lab, an independent record of 103 film families.

What I do for manufacturers

Field evaluations
A new product, a new batch or a roll you aren't sure about goes onto real vehicles with working installers. You get a written report with photos, measurements and a plain verdict: sell it as is, sell it with a note, or pull it.
Spec sheet and claims review
Installers trust numbers they can check. I'll read your data sheets and marketing claims the way the trade reads them, and show you what's missing before a competitor or a forum thread points it out.
Installer and dealer insight
What shops say about your film when your rep isn't in the room. Where it wins, where it loses, and what would change their mind.
Training and launch support
Install guides, dealer trainings and launch events that installers will actually show up for, delivered by someone who has done the work.

Field evaluations

Every manufacturer ends up with film it isn't sure about: a roll wound wrong, a batch with a cosmetic flaw, a new construction nobody has installed at volume. Scrapping it is expensive. Shipping it blind is worse.

  1. You send the product and the question. What changed, what you're worried about and what a pass looks like to you.
  2. My installers cut it and put it on real vehicles, under normal shop conditions, the same way your dealers will.
  3. You get the report. Photos, measurements, who did the work, and a verdict you can act on.

Consulting never buys a grade.

I also run the Film Lab, where every film family gets an evidence level based on what its maker publishes. That level is calculated from your public documents and nothing else, so the only way to raise it is to publish better data. I'm glad to help you do that.

Consulting clients are disclosed wherever their film appears on this site.
