During the last wash of the truck I noticed some swirling on the hood. It seemed that it was the only panel that I could really notice it on too. My question is can I somehow just clay the hood and put on some #80 and rewax the hood. Will it look too different or should I just redo the whole truck. The last claying was two months ago.

To prevent future swirls I'm changing my washing method after some recent threads.

 

If it's light, try going with something like a quality cleaner wax but, to your point, yes... you could go that route and I seroiusly doubt that you'd tell a huge difference between body panels.
