I guess if you enjoy spending 2-3 hours washing & waxing your car with all the different products you need.. Bucket, soap, water, hose, sponge, lg towels. windex, wheel cleaner, wax, applicators, more towels, etc..
If thats the case, maybe Dri Wash n Guard is not for you..
I prefer to Use 1 product on the whole car in 30 minutes.. and get 2 hours of my life back.. And for some of us who live in a cold winter climate, Dri Wash n Guard can be used to clean outside or in the garage.. Not all of us can wash the car on the driveway in the winter and for those in apartments with no water access, its perfect..
