crack in the fender..

this weekend i washed my car, had it parked outside my work and was rotating my tires around, and i noticed on my front left fender, i have a minor hairline crack at about mid point of the wheel. its only about a inch or less in length. is there anything i can do since its so small or am i stuck with either living with the tiny flaw or buying a new fender? im trying to keep this car pretty much flawless for once in my life and that just brought me down.

well
these cars have stress cracks...
i have noticed where the body rolls around top by the t-tops that there are little cracks about looks like a hair..

this is just from the body twisting on load.and it streches the paint and cracks..

but on a front fender...never seen anything there..
connectors would stop it....

you would be able to have it sanded down then repainted..there would be no need for a new fender...
