Expert Verdict — Reviewed by the SuperArbor Pro Desk
Detail work is where coating systems most often fail, so a high-build elastomeric mastic like PolyBrite 73 is worth specifying over generic mastics. Apply it generously into laps, terminations and fastener heads, then embed reinforcing mesh where the system calls for it before the reflective top coat goes on. Order enough pailage for the full detail scope, as thin or skimpy applications are the common cause of callbacks.
Wear gloves and eye protection when handling liquid mastics, and follow the manufacturer's safety data sheet for ventilation and disposal.
