Competition is a welcome challenge to Perma-Glaze^?/sup>. It means that a market for your service already exists in your area and it helps to promote the industry in general. Most competitors, however, use either an epoxy based finish, which yellows in time and easily chips and peels, or a thin urethane coating which contains lead and/or polyisocynates, which are extremely toxic and require the use of an air fed respirator during application. These urethane coatings are actually intended for automobiles and aircraft; they are not designed for bathroom and kitchen environments.
