Ron@Optimum Posted September 2, 2021 Share Posted September 2, 2021 Opti-Lens, like other coatings, needs 7 days for chemical resistance to develop, so applying Opti-Seal or Hyper Seal (the new formula) can be added 1 hour after coating to protect Opti-Lens.

If on the other hand the coating is new and not oxidized then you can apply Opti-Lens on top of it to prevent oxidation. That is why there are two different answers depending on the condition of the headlight. Many thanks, Ron and Dr G, for explanation. My detailer applied OptiLens to my headlights when they were brand new, so hopefully it will keep them from yellowing. Quote Link to comment Share on other sites More sharing options...
