The ACF-50 is an exception to this rule, of which we are firmly convinced. The fluid developed for aviation penetrates through the rust to the core, lifting it off the metal surface and enclosing it. This deprives the rust of nutrients and stops the ongoing process. Due to its creeping function, it settles in gaps and gaps and prevents corrosion in these gaps. This of course makes it ideal for protecting the centre tunnel of the Vespa from internal rust, especially on the overlapping sheets. The magazine scootering in England has made a vivid practical test, and nailed a treated with ACF-50 and an untreated metal sponge to a board in the garden and exposed it to the tide. The untreated sponge had rusted away and disappeared after some time, while the treated sponge showed no rust traces after three years. An impressive demonstration of its performance.
The manufacturer recommends renewal every twelve months. The ideal product for protection against rust and corrosion in oldtimers and new vehicles.
The simple application is particularly convincing, requiring no special tools and heat or similar.
