In the field tests we ran at school it was far superior in rust
prevention to all other aerosols.

We cut 8 pieces of 1" square tube, ground them clean and clear coated 7
of them with various products.
The eight was left bare for a control.
All the tube pieces were hung on our outside chainlink fence that

They were left there for 6 months from October to March.
