Hi Newbury,
Does $0.21/ounce vs. $0.23/ounce for the 5 gallon pail, $0.46/ oz. for the 1 gallon pail, and something between $.80 and $1.??/oz. for the aerosol make you more likely to buy it?
For me, the 5 gallon pail sounds like a better compromise to expending a grand and a half for more than I'll likely ever use.
I went to the Kellsport Mfg website after googling it, and somewhere found a link to give them my email in return for them sending me discount coupons, but when I tried to get back to it, I couldn't find it again.
They also list several different formulations and as someone else said before, they really sell it as a corrosion resistant coating rather than strictly as a lube product.
Happy and safe tractoring,
Thomas
