Ditto using Rejex (protectant) over clearcoat and on windows. Yes it may stay shiny without, but it aids in removing bugs and repelling water for quicker drying. New clearcoat should finish cure for appx 2-4wks depending on who/how/how many layers was applied prior to sealing with something. 303 Aerospace Protectant on the fiberglass roof and rubber for UV protecton.
