Clear coat, or not, I've had great success using modern polishing / rubbing products, followed by modern wax or protectant. So, in answer to the original question, I'd say 'yes', give it a try. Can't hurt. And, if you are apprehensive, try it on a small discreet area.
Apology not needed. Pay no attention, as needed.
(I think you will find that there are several guys here, that have clear coat paint on their old Fords, even back pre-war and beyond. So, in my book, you question is easily justified, even though I don't think there is any reason for 'justification'.)
