Both Fluidfilm and Penetrol can protect metal from further rust deterioration and enable our fire pits/rust bowls to be used as water features.
FLUIDFILM
Fluidfilm is lanolin-based. According to the manufacturer, it is a single application barrier (can only be removed by wiping it off). It is safe, and in fact moisturising for your hands; it is also safe for animals/pets. Fluidfilm is also very useful for maintaining gardening tools as the lanolin not only protects the metal, but it is also a lubricant.
We range 2 different thicknesses of Fluidfilm:
Spray on – should be used for garden tools
Thicker product – better to coat metal bowls to transform into water features (paint or roller apply)
From our experience though, Fluidfilm does leave a greasy film on the surface of the metal it is applied to, so it is best to apply it sparingly; a little goes a long way.
PENETROL
Penetrol is a petroleum-based product, and therefore evaporates so the product might require reapplication.
With 2 applications (using a small painting roller), Penetrol gives a non-greasy result which seems to last for quite a while.
