Paint & Body Work - Rolled fender crack

So my friend rolled his fenders today...and one fender turned out great, the other fender was good to but the paint cracked a little bit...it is underneath so you can't see it...not worried about it now, but worried about it spreading out into view later on.

What can stop it?

pics would help.

Pics won't stop it, but since it's on the underside, sand that spot down and hit it with a touch-up brush. Noone will see the repair, but if you want a better finish, then let the paint dry and sand it smooth with 800 or 1000 grit or both if you really want to take the time. Then hit it with 3M Rubbing Compound on a rag (by hand). That should do it. Just make sure when you sand it the first time, sand out the whole crack.
