you cheap guys out there looking for 100oct need to look into this:
http://torco.com/index.php?page=shop...mart&Itemid=32
forget about W/I, IMO its just a 100oct bandade that may or maynot work....torco works I can say that for sure!!!!
you can get 20 full tanks of 100oct out of one 5 gallon pail of torco, and for only $150..you do the math........
