Removing fingerprints from epoxy can be a delicate process, depending on the curing stage of the epoxy. For uncured epoxy, gently wiping the surface with a cloth dampened with isopropyl alcohol can remove fingerprints without damaging the finish. Ensure the room is well-ventilated during this process. For fully cured epoxy, a more careful approach is needed. Lightly sand the surface with fine-grit sandpaper (200-400 grit) to remove the fingerprint, followed by a higher grit (600 or above) to restore smoothness. After sanding, clean the surface with a damp cloth to remove any residue. Applying a thin coat of epoxy or a polishing compound can then restore the shine. It’s essential to wear protective gloves during these processes to prevent further fingerprints and to ensure your safety.

Adhering to polyethylene surfaces can be challenging due to their low surface energy, which makes most tapes struggle to stick effectively. However, specialized tapes designed specifically for this purpose, such as those utilizing high-performance adhesives like acrylic or rubber-based formulas, can achieve a strong bond. Manufacturers often produce tapes explicitly labeled for plastic or polyethylene, including duct tape, some types of packing tape, and specialty polyethylene tapes. Another solution is using an adhesion promoter or primer, designed to increase the surface energy of polyethylene for improved tape bonding. It is crucial to ensure the surface is clean and free from any contaminants before application to maximize adhesive contact and effectiveness.

As of my last update in 2023, there isn't a specific Virginia state law that exempts computer ink from sales tax permanently or during a particular weekend in 2017. However, Virginia does host an annual sales tax holiday, typically in early August, which exempts certain school supplies, clothing, and energy-efficient appliances from sales tax. In 2017, if computer ink was included in the list of exempt items for the sales tax holiday, it would have been tax-free during that specific weekend. To confirm, you should check the Virginia Tax website or consult with a local retailer for the exact details of the 2017 sales tax holiday. If computer ink was not included, then it would have been subject to the standard sales tax rate. It's always a good idea to plan your purchases around these holidays to save on taxes.
