Is a structural resin filler. Often referred to as “flox” it is used in structural joints and in areas where a very hard durable build up is required. Flox is mixed in much the same way as dry micro but only about two parts flock to one part epoxy is required. Mix in just enough flock to make the mixture stand up. If “wet flox” is called out, mix it so it will not sag or run. “Flox” is often used to reinforce sharp corners to give more structural integrity. The flox corner is done just before one glass surface is applied for a wet bond to one surface.
