What are the challenges of achieving glossy finishes on polyethylene sculptures?

Achieving a glossy finish on polyethylene sculptures presents several unique challenges due to the material's inherent properties. Polyethylene is a low-surface-energy plastic, which makes adhesion difficult for paints, coatings, and polishes. Its non-porous nature resists absorption, leading to uneven application and potential peeling. Additionally, polyethylene is sensitive to heat, limiting the use of high-temperature polishing techniques. Chemical resistance further complicates the process, as many solvents and primers fail to bond effectively. To overcome these issues, specialized surface treatments like flame or plasma treatment are often required to improve adhesion. Even then, maintaining durability and consistency in the glossy finish remains a significant hurdle for artists and manufacturers.
