The Resources section is a maintained reference directory. Inclusion means that a source is relevant and useful for flat-glass window-film work; it does not mean Precision Film Systems endorses every statement, product, organization, or community discussion.

## Preferred sources

- Current manufacturer-owned documents and support routes.
- Government agencies, standards publishers, certification programs, national laboratories, and established industry associations.
- Original technical papers, tools, and customer information from accountable publishers.

## Recommendations and review

- People may recommend their own resource or one created by someone else.
- Every submission is reviewed case by case for relevance, accountability, source quality, classification, currency, and practical usefulness.
- Submission does not guarantee acceptance, a response, placement, endorsement, or continued inclusion.
- When a third-party resource is accepted, the directory points visitors to the original publisher; the recommendation form is not used to collect material for copying or republication on the Precision Film Systems website.

## Separate classifications

- Technical authorities, government guidance, standards publishers, associations, media, and communities are labeled differently.
- Manufacturers, manufacturer-owned brands, suppliers, distributors, and specialty providers are not presented as interchangeable.

## What is not included

- Copied or rehosted third-party documents without permission.
- Generic search directories, scraped copies, unsupported product claims, or links added only to increase the directory size.
- Individual social posts presented as permanent technical guidance.

## Verification

- Each maintained entry records a last-verified date and status.
- Redirects, blocked automated requests, logins, and timeouts receive normal-browser review before status changes.
- Visitors can report a broken link to support@precisionfilmsystems.com.

## Independence and commercial relationships

- A normal editorial link does not imply affiliation, approval, or partnership.
- Any paid placement, referral arrangement, supplied consideration, or other material connection must be disclosed clearly near the applicable listing.

## Compatibility and warranty

- Precision Film Systems does not create independent film-to-glass approvals or rewrite manufacturer warranty terms.
- The current manufacturer source and exact installed configuration control.
