Recommendations for waxing/protectant on 68′ 300 Grill

I have almost completed in my recondition/paint of the 300 grill. Going on about 12 hours and 80% done, not wanting to do this again. Oil based paints applied. An effective traditional wax and buff would be difficult due to the corners and small spaces. Given the intricate design, was wondering if anyone has any recommendations as to a protectant/wax/spray wax that could be applied to seal the paint? Thanks.
