Jewelultra has issued a response to the news of an advertising watchdog ban on its claim of protecting against bird dropping damage.

It has supplied a report from an independent testing organisation, Intertek, which in June tested body panels treated with Jewelultra's Diamondbrite paint protection system.

Intertek's report states that pigeon droppings, or guano, fell off readily and the specular gloss of the treated panels was maintained, compared to the untreated panels.

AM-online reported yesterday that the Advertising Standards Authority had told paint protection suppliers Jewelultra and GardX they hadn't proven their claims that their products helped to protect motor paintwork against damage from bird droppings so could not repeat such claims until they had evidence.

It followed a complaint to the ASA from rival supplier Autoglym.

AM understands that Jewelultra has supplied the ASA with the Intertek report.
