warbirdguy, its well to say just do............, but to be honest, I would NOT want to keep either silicates or milled f/g around, especially if you have kids, and for the convenience of having the thickened varieties handy , I'd be more than happy buy it. By all reports, its simple, easy to use, stronger than needed and also has a warranty. The way I see it, i couldnt ask for more.
