Heres the scoop between Rustoleum Paint, ( made in the USA), and Tremclad Paint, made in Toronto Ontario Canada (aka Hogtown). The Rustoleum Corporation USA owns the Tremclad operation in Canada. The Tremclad paint is made in Canada in thier plant in The City of Toronto. It is a very diffferent paint than Rustoleun, both are made, sold and marketed as a rust paint, that you can use over metal wood fibreglass,wives , kids, bosses etc, sticks like!!!!!!!!! to a blanket. The resin in Tremclad is of a long oil base in chemical nature, thus does well when thinned with mineral spirits. The Tremclad company recommends you thin this paint to 10% for the purpose of spray application, usually 1 or 2 coats. The roller technique, employed by people like us was unknoun to the Tremclad chemists. But they did state, that by using the paint this way would infact create a very good bond,very hard surface and a nice finish to work with. So I believe Charger has been very ingenious in discovering this method, ( should be patented), so hats off to you Charger. Now getting back to the Rustoleum paint made and sold in the USA, it is of an arcrylic resin in its basic chemical make-up, so there is definately a difference in the 2 paints, which could be why some results in this application may vary. I hope this helps some of you guys with your questions. You will not be able to buy Tremclad in you retail stores that sell Rustoleum, but you could have Rustoleum order it for you I believe.......Roll on Brothers Roll on!!!!!!!!!!!!!!!!!!!!!!!!!!!
