Removing Contamination

This week's tip:

Ever have a contaminant trapped under the film? Okay... so you're a 'Pro' and you don't get contamination during installs.

Well for those that do (tell the truth)... have you had that opportunity to lose sight of where the contaminant was once the film has been pulled for retrieval?

You can use the babies pictured below to mark where the contaminant is located, making it much easier to find once you've pulled back the film.

The grease pencil marks wipe off easily with a dry towel after the film's been reinstalled into position.
