Sonax Xtreme Brilliant Shine Detailer

Overall Auto Express rating

4.0

Best price: £8.99 Size: 750ml

Excellent test debut for Sonax’s detailer. Big pack makes it one of the most cost-effective sprays on test, but that’s not the only reason why it pushed our winner hard. Brilliant Shine and QED were the standout performers in the water beading assessment, and their sectioned off strips were easily identified when the bodywork had dried, with fewer water marks. A finer, wider trigger spray would make this a winning package.
