You can see the haze building on the fibreglass. The paint's gone a shade duller since last summer. You know it's oxidation and you know it's only going to get worse if you wait. This 473ml Premium Cleaner & Wax with PTEF does the heavy lifting in one step: strips the oxidation and hazing off fibreglass or painted surfaces, then the PTEF polymers seal that restored finish so UV rays can't chew through it again. Apply by hand or with a buffer, let it haze, wipe off. You get a deep gloss back and a layer of protection that actually holds. For the best long-term result, follow up with a coat of Premium Marine Polish with PTEF
