I like to use Meguair's Gold Class Carnauba Plus Premium Liquid Wax and im wondering should i apply that first and than apply hybrid ceramic liquid wax on top of it? Also is there any benefit letting the hybrid ceramic liquid wax dry for more than 3-5min like the directions say? Does HCLW have to be cured for 24hrs before exposing it to rain? Can you use HCLW on headlights to help with fading and yellowing since it has uv protectant?
