Based on internet reviews alone I decided to buy 2 bottles of 8oz Kroil Oil. However I live 10000 km away in Denmark/Europe and you cannot buy that stuff in Europe. Thus, I imported the two small bottles and paid huge amounts for shipping and import tax.
This is truly the best stuff. Nobody knows it here. People just spray huge amounts of WD40 everywhere (or similar copies of WD40) and when I tell them about the wonders of Kroil Oil they just look at me like a nut case.
Here in Europe, at least northern Europe, WD40 has became such an established brand that people dont say "rust penetrating oil" anymore, but just "WD40" and everybody knows what they mean. People just spray WD40 or similar products everywhere and still snap bolts/nuts all the time. They have no clue.
But I don't like the smell of Kroil Oil at all. It smells very synthetic and chemical and tends to hang around for a long time.
I use a plastic pipette with my non aerosol Kroil oil and manage to control the amount used very precisely - also upwards to some degrees. I think if you are using a pipette to make precision applications a 8 oz bottle will serious last a lifetime.
