What promises to be a boon to the automobilists of the valley is a new preparation called "E and W Puncture Sealer" now being introduced by Chas. Gay and J.M. Suttor. Several hundred punctures have been made in the casings of Mr. Suttor's car for demonstration purposes and the tire stands as inflated and solid as ever.
The mixture is in the form of a liquid and automatically seals punctures, all that is necessary being to remove the nails and give the wheel a whirl. About a quart of the sealer is poured into the inner tube then inflated as usual.
Large crowds have watched the punctures and inflating of a tire that had over 2,000 punctures with the fluid, and then saw it pumped up to a pressure of 75 pounds and hold the air as well as a brand new tire. It sounds almost impossible to do this, and many people were dubious until after the proof. That E&W will be a boon to auto owners is assured and a large sale is predicted.
E&W treatment is a simple process applied by any motorist and is guaranteed to prevent leakage of air from punctures or porous tubes. It does not fill the tires and adds very little weight to the car, in fact, about 5 to 8 pounds, according to size.
E&W is a semi-fluid which is injected into the inner tube through the valve stem, making the tube self-healing. It retains its semi-fluid state at all times and under all conditions and temperatures, it closes punctures by sealing the opening instantly and automatically. The air pressure with the tire forces a portion of E&W into the puncture, thus closing it before the tire loses its normal pressure.
