Sorry to hear this has happened to your Jeep - what year is it, and is it original paint on the hood?
As said above, sounds like "crows feet" = clear coat about to go south. Sometimes it still takes awhile to get worse.
I remember back in the mid-80's Chevrolet painted a slew of new cars and trucks wrong and they all failed almost at the same time a year later or so, and they had to repaint everyone's vehicle again.
If you dont have a warranty, you may have to sometime, find a really good shop, talk to the Owner, find out what your options are, look at some of his paint jobs, and have it done. You might want to get up to the roof and see if its doing the same thing there too. Way better to get it all done at once than a panel at a time.
Good luck with this !
