Only one problem with Meguiars Endurance Gel; it's oil-based and contains petroleum distillates, meaning that regular use will tend to dry out your tyres, leading to browning and cracking. No doubt it looks nice and lasts well, but our choice would always be a water-based product, in order to prevent any long term degradation of the rubber - important on performance cars! For a very similar look and longevity to Endurance, Blackfire Long Lasting Tyre Gel ticks all of the right boxes, while for a more natural satin look, Gloss It's new Signature Tyre Gloss is simply awesome.
