"This vendor sells only one item that I know of - A paint additive that increases the reflectivity and emmissivity of paint, thus making standard paint into a poor man's thermal radiant barrier - which hekps keep a home warmer in winter and cooler in summer if intelligently applied.I ordered a small quantity of the additive and tested it in a "hot box" of my own design and determined that it does work - it makes a difference in how much heat moves through the walls of the box within a given time compared to the same paint without the additive. Thus I am now ordering larger quantities to use on my home. This additive, ceramic microcapsules, is available on several web sites but koolcoat is by far the best price, less than half of most of the others. The only reason I really have to recommend this particular vendor is price. The web site is quirky, payment can only be made through paypal (forcing you to open an account if you don't have one) and customer service is non-existant (emails, voice mails go unanswered).I suspect it's some guy operating out of his garage and ordering this stuff in industrial lots then dividing it into smaller quantities as orders are received from the web (the product arrives in big household zip-lock bags). The only shipping option is USPS slow boat, so delivery is one-two weeks, and you have to plan ahead if you want to include this in your household painting projects.Still, its a very good price compared to other vendors and worth the quirkiness and the wait for significant savings when deal with large quantities of additive for large paint jobs."
