Material Transparency - ABS vs Perspex vs Fibreglass:
Perspex is chosen for its clarity, UV stability, and long-term resilience. It's also 17x— stronger than glass - compared to ABS, which is only 2-3x— stronger - making it ideal for smoked finishes that last. Unlike ABS, which may fade or chalk under prolonged sun exposure, Perspex maintains its smoked finish and structural integrity. Fibreglass, while heavier and more labour-intensive to prep, is ideal for enthusiast builds and paint-matched applications due to its rigidity and shape retention.
