Let me ask you a question

Posted On: June 02, 2017


We want to now...What is your favorite material to use, and why? 

Lets throw a twist into this question, would you be willing to try something new? What are you looking to create today. There are so many great products out there to make so many cool things.  Lets start with a material that actually floats in water! Yes you read that correct, IT FLOATS!  Is called Feather Lite, and you can make some very cool items including fishing lures.

Shawn Rutledge, an inventor of unique fishing lures, has found success, and scored some big fish with his lures. Having been an avid fisherman his entire life, his passion for creating fishing lures lead him to the Smooth-On Technical Helpline in search of materials. After considering various options from their product line, Shawn settled on Feather Lite lightweight casting resin and Smooth-Cast® 320 casting resin. He found that a combination of Feather Lite resin and Smooth Cast 320 resin provided the perfect degree of buoyancy needed for his lures. The resins were very easy to use and paint, making his design options limitless.

Shawn started his own company, designing and producing the lures in his backyard, working with Mold Max Silicone, Feather Lite lightweight resin and Smooth-Cast 320 casting resin. Since then, he has developed an entire line of lures and gained almost a cult following.
