I just finished up the last of my McGuire's Qwik Detailer. This was my first go at a spray-on quick application detail spray for my car. I have used them on my Harley when I had it. Let me start by saying, it works well. I use it mostly for the door jams and where car washes miss. Sometimes I'll use it when I am just showing my Subaru off at a local meet to bring the shine back. Application is simple, Spray the detailer on to the paint, and using a soft cloth ( I recommend microfiber or terry cloth) wipe the spray and dirt off the car. I a bottle up for around $5.00-6.00 at my local auto parts store and it lasted me quite a few months. Please not this is not the "lazy person's car wash in a bottle." using it that way can screw up your car's paint. you can also use it on your boat or RV. I would give this product a 5 star rating, I love it and for the price, I challenge you to find a better product.
