Mankiewicz, a leading German paint manufacturer, created the Alexseal Yacht Coatings system to simplify the painting process while delivering aerospace-quality performance. Alexseal offers a complete system from fairing to finish. Their Premium Topcoat 501 is a polyurethane that applies as easily as a single stage but offers the durability of a two-stage system, and notably, it is repairable and buffable, unlike many other linear polyurethanes.
