Great for building cedar or strip-built canoes and kayaks

9 oz/sq yd weight allows multiple layers while maintaining reasonable laminate thickness for complex layup schedules

It features a coarse 60-grit on one side

Here is some information about the use of styrene thinner in composites:

Thixotropic Silica Options:Carton (7 lbs) Minimal polyester fill threads onA white, free flowing powder, Thixotropic Silica is a thickening agent primarily added to resin to prevent run off and sags on vertical surfaces. Use with an epoxy to produce extremely hard, solid parts, perfect for structural bonding, filling, and filleting. Use in conjunction with chopped glass fiber for added strength for parts. Silica filled resin can be difficult to sand. Consider using #22 Glass Microspheres for areas that require sanding. This
