Applying epoxy to a refrigerator is a unique way to revamp its appearance or repair surface damage. First, ensure the fridge is unplugged and cleaned thoroughly, removing any grease or residue. Sand the surface lightly to help the epoxy adhere better. Mix the epoxy resin according to the manufacturer's instructions. Apply a thin, even layer using a foam roller or brush, starting from the top and working your way down. If you're adding decorative elements like glitter or paint, now is the time to incorporate them before the epoxy starts to cure. Allow it to dry as per the product's recommended time. It's crucial to work in a well-ventilated area and wear protective gear like gloves and a mask.

The term "polymer lower" typically refers to the lower receiver part of a firearm, particularly in AR-15 style rifles, made from a polymer rather than traditional aluminum. The use of polymers can offer several advantages: they are generally lighter, can resist corrosion better, and can be less expensive to manufacture. However, there are trade-offs, including concerns about durability and long-term wear, especially under heavy use or with powerful calibers. Polymer lowers have become more reliable over time thanks to advancements in materials science, but they may not satisfy all users, especially those who subject their firearms to extreme conditions. Ultimately, whether a polymer lower is "good" depends on the specific needs and preferences of the user, including factors like the intended use of the firearm, weight considerations, and budget.

Yes, titanium dioxide is also known by several other names including titania, which is its most common mineral form, rutile. It is often referred to in the context of its application or chemical formulation. For instance, in the realm of cosmetics and food, it may be listed as E171, a food additive code. In industry, it might also be called titanium white, particularly in paint and coatings due to its superior opacity and brightness. This versatility in applications from paint pigments to a UV filter in sunscreen underscores its critical role across different sectors.
