What does it mean ? How is it done ? Any pictures anyone ?

Just curious

Thanks

 

it means to roll the inner lip of the fenders to eliminate wheel rubbing. some people trim the fender. i have seen rolling techniques including using a baseball bat with the tire for leverage ( i wouldn't recomend this, but some people have done it without problems). there is a tool made specifically for it as well. the main problem with rolling fenders is the possibility of cracking the paint, this can be made less likely by heating the paint prior to bending. try a search if this didnt help enough, there are a ton of posts on it.
