Does hood protector really helps?

[sobi6111]

I am about to paint my car's hood,fenders and bumper front,so the thing is that i can't put clear bra on it right after being painted,as paint needs about 20-30 days to cure compeltely. But i don't want to damage it with Idaho rocks on the road in 1st day after paint. So should i buy hood plastic protector to save paint from any damage for a month till I am able to put clear bra??? Any ideas or suggestions are welcome :-)

Anyone have picture how it looks white car with hood protector? In closely shot :-)
