I'm glad I am not the only one who didn't read the instructions and had burningly irritating Levis, soaked with just enough Fluid to start itching & burning gradually, leaving one with the idea that it's soon stop ... and it only getw worse and worse ...
Today's Zippos have a little Instruction printed on the top filler pad to remind to lift it and not fill higher than the flint screw.
Her are where I bought my Pure, Armour (50% heavier case), Polished, 100% Brass Zippo and Belt Loop Leather Carrying Case -- all Leather with Snaps made in USA (both delivered from Louisiana two days later): http://www.knifeworks.com/index.asp?PageAction=MFGSEARCH&ManfID=1077&Page=3
Here is where I bought Zippo Fluid, Wick, Flints (6 for 69¢) -- Lighters here too, just a bit more expensive): http://zippocasemuseum.com/index.aspx?tabindex=0&tabid=1&productid=392&directoryid=-1&ctrl=productdetails
The Zippo Fluid ("New Formula") smells more like natural Gum Benzoin and perhaps a little more pure than the deadly old Ronson stuff that stung me.
GOD Bless !
