Thanks guys. When I Google hammer tone there are dozens of additives to specifically make the hammer tone effect put out by dozens of companies but they are for industrial applications. One product comes in 180 kilogram pallets! I had heard of folks adding Toluene to paint to get the effect, (see Sheridan's 46Chevytruck.com). Lots of info on wikipedia under
http://en.wikipedia.org/wiki/Hammer_paint. Wikipedia says, "To make the "hammered" effect more pronounced, a small percentage of silicone oil may be added directly before application." This is consistent with what I read because silicone oil is polydimethylsiloxane and that ingredient is common to a lot of the industrial products. Silicone oil is available locally and I think it is in Armour All. I think experimenting with concentrations of about .05% by weight is a starting point. Deve, I like your heater (and your website!). I'll probably use that same color you used since that is really close to my interior color.
