[Partner General Resources](https://hub.geminimade.com/knowledge/partner-resources?hsLang=en#partner-general-resources) September 17, 2026 # Harsh Environments ### Does Gemini’s Lifetime Guarantee cover letters and logos installed in harsh environments?  As stated in Gemini’s Lifetime Guarantee, we guarantee all products for life. If any Gemini-manufactured letter or logo fades, breaks, or contains any defect, we will refinish or replace the defective materials at no cost. Products must be installed in their original location for our Lifetime Guarantee to apply. **Note:** It is crucial to the longevity of the sign to note the installation environment when selecting the material and finishes.  Gemini has a wide range of products from UV-stable and chemical-resistant (formed letters, anodized aluminum, and painted products) to the most susceptible to failure when placed in harsh environments (polished brass, brushed aluminum, and laminated letters). Impact resistance is also an issue against standard wear and tear. To that point, anodized aluminum is our most durable in the broadest range of environments. Acrylic letters made are more prone to break than those made from CAB plastic (formed plastic) or metal. Despite our best aluminum alloys, powder coats, and finishing techniques – aluminum remains reactive and will degrade when placed in an area with moderate UV exposure and harsh chemical or excessive moisture contact. The only way to ensure that aluminum letters do not corrode is to anodize the surface of the letter. Anodized aluminum is superior to 316 Stainless steel in coastal climates. - [Quote and Order Lead Times](https://hub.geminimade.com/knowledge/quote-and-order-lead-times?hsLang=en) - [Partner Portal "How-To" Articles](https://hub.geminimade.com/knowledge/partner-portal-how-to-articles?hsLang=en#main-content) -
