Well known product in the motorcycle world, and highly thought of.
But it definitely isn't something to "slosh" around, not that it would be harmful, But because (a) it's
expensive and (b) it doesn't work well applied over dirt or greasy surfaces
so would be largely ineffective, and wasted if used over acres of intact painted steel
unlikey to corrode. More a product you apply to selected cleaned up metal, chrome,
anodised surfaces to protect from corrosion.
