I tottaly agree with detailing the fenderwells but when it is cold and snowy, you just want to finish ASAP. Fender wells are not a priority in the winter. Getting salt off is. Wash days are hard to come by, especially for those of us that prefer hand wash only. Also, I would stay away from amour all since it has sealants. Get a good vinly / rubber conditioner. Griot's garage sells an excellent one.
