Just when you thought it couldn't get any better: Smith's Fill-It Epoxy Filler now has a new, softer consistency! Same great long-working-time. Same great hang-in-place performance. Same great ease of sanding or carving. Same great cold-weather-cure. Same great price. When you want the very best: Smith's Fill-It. Hello. I'm Steve Smith. Thirty-five years ago I invented The Modern Technology That Restores Deteriorated Wood. Fill-It is an essential part of that technology. It works for two reasons: It is about as flexible when cured as the wood itself, and my resins are made largely from the natural resins of wood itself. Using something that works isn't just a good idea, it's a necessity. We invented it. It's a fifty-fifty mix. It comes with simple directions. You can buy it. You can use it. Call, e-mail or write to 5100 Channel Avenue, Richmond CA for more information. We can answer your questions. Smith's Fill-It is a non-sag epoxy filler for restoration of wood. Easily sanded. Cures overnight. Smith's Fill-It epoxy filler represents a breakthrough in the technology of filling compounds. Through the use of advanced hydrogen bonding technology, we have produced a high strength, light weight, non-sagging, easily sanded epoxy filler. It consists of an epoxy resin and a curing agent which is derived from natural wood resins, and so is very compatible with wood. The two components are designed to mix one to one by volume. When mixed they become a gel which may be faired and worked to a feather edge. After one to two hours in moderate weather it begins to harden, and cures overnight. As soon as it does not gum up the paper it may be sanded, and primers or paints applied. It is easily carved or drilled, and screws may be driven into pilot holes without cracking. It has sufficient compressive strength that it maybe be used to fill defects in ferrocement boat hulls, and sufficient flexibility that it is suitable for wooden beams, windows and sills, doors or other parts of wood buildings as well as wood or fiberglass boat hull repair. This product was invented by a physicist and aerospace engineer (with thirty years experience in the aerospace industry). It was designed to meet the same formulation standards as aerospace materials. It contains an aerospace adhesion-enhancing additive to give it aggressive and tenacious adhesion to wood, cement and a wide variety of materials. It is reinforced with glass fibers for extra tensile strength. In fact, all of the solid fillers or reinforcing additives are chemically engineered glass of one form or another. This gives the best long-term stability and moisture resistance. In 1992 this product was upgraded, incorporating Smith's new Dual Synergistic Catalyst Technology. This gives a longer working time and shorter full cure time. The new technology also ensures an absolutely dependable full chemical cure at temperatures as low as 28°F (-2°C).
