These are the same type used by Jeep for the same job....costs $7 each clip @ Jeep if I'm remembering correctly plus their 2 hours of minimum Labor.....My research, which included, Professional Parts personnel for this type of product led me to purchase and fix my own fender/ wheelwell issue. Job done in 15min to 1/2 an hour tops and that was taking my time. Looks great, Jeep in great repair status...yes..taken through automatic car washers, up to the maximum legal speed limits of the area's driven...80+ mph and not a single problem!!!!Awesome product!!!!!!!
