ooh! Oh yes, I read that, Chuck and now I am checking it out! It sounds to be more substantial than the Fluid film...
Wizards ? POWER SEAL TM is an easy-to-use liquid
sealant that preserves the beauty of polished metals
against corrosives such as ordinary air, humidity,
water spray and road contaminants such as salt and
lime. A bonus with POWER SEAL TM is that it buffs
to a long-lasting, slippery, high-gloss finish that will
maintain the shine and protect all types of metal sur-
faces*. This product is designed to give the highest
luster possible requiring the least amount of effort.
I'm taken by the claims and results enough to want to buy a tin, but there seem to be no stockists here, although Wizard's themselves appear to sell other stuff via UK Amazon, so I've enquired.
In the absence of that, I'll just polish and wax and clean regularly. Horrors.
