I have not done this to my vehicles but given that the F150 is a blunt object pushing through the wind I may do this to avoid stone chips etc… Has anyone done this and do you recommend doing the whole hood or just the “nose”(and any issues doing the whole hood in terms of it not looking consistent with the paint on the rest of the truck — same thing if I just do the front bumper / facial and the front section of the hood only, is the invisible line, so to speak, noticeable and will that creates some differences in fading or paint colour versus the untreated areas in your experience. Thanks.
