If you have not used a clay bar, I can tell you that it really does work and it is extremely easy to use. Do not be afraid to complete a few extra passes with it. This is actually step 3 out of 4 steps. The first is to wash your car, then polish it, then clay bar the car, then use Megiuars Tech 2.0 polymer sealer. The clay bar step is actually effortless. You just have to remember not to drop the clay, and do extra passes/wipes, a small section (12&#34; x 12&#34;) at a time. The last few passes with the clay bar you can use the weight of the clay itself. One reviewer wrote that this was too mild and it did not remove a lot of contaminants. This is because he may be missing the &#34;polishing step&#34;. The &#34;contaminants&#34; should come off with the washing and polishing. The clay bar is for removing fine contaminants. Your paint will be very smooth and silky. That is no joke either; it really feels smooth. The car will then be ready for a polymer-sealant or a wax if you prefer.In Summary: Step 1 Wash your car with Megiuars Gold Class (better than the stinky yellow hazy Meguiars Ultimate Wash). Step 2 - Polish it with either of the following depending on the contaminants. Feel the paint. Is there a lot of grittiness ? Then you may want to use Megiuars medium/fine cut cleaner. The medium cut cleaner will remove some heavy duty water spots that you just cannot get out with anything else. If you do use the &#34;medium cut cleaner&#34;, then you may want to use a &#34;swirl remover&#34; after this step. If your paint feels all right (a small amount of grittiness), then a normal &#34;polish&#34; (Megiuars Ultimate Compound is great) will work just fine. Helpful hint. Purchase an inexpensive sponge, not a real loop sponge, one of those large smooth cheapy sponges for $1.75. If you use a round hand applicator, you may obtain a zebra stripe pattern. The zebra pattern means that the product is working, but your fingers are smashing down more than the applicator portion in between your fingers. You need an even pressure and your large cheapy sponge will achieve that. I also tried a large circular sponge applicator for my drill and that actually worked very well and it saved my arm a bit too. The circular applicator for my drill achieved the best results. I had major hard water spot damage that I just could not get out. Always remember that even though the paint appears very good after this step has been completed, do not stop at this step. There is no protection and your paint needs it since you just removed the protection. Step 3 - Clay Bar your car - use this kit or &#34;Mothers&#34;, although since I am writing a review in Megiuars product, use it. It works very well. Follow the directions. Use medium to light pressure. The last pass can be the weight of your clay and hand. I usually use 10-12 passes. Do not be afraid to make extra passes. The clay is really non-abrasive, and almost effortless to use. Complete the entire car. Do not drop the clay. If you do drop it there may be some grit hiding in the clay and you will scratch the heck out of your paint. I have used it after I dropped it, but it is a hassle removing the top layer of the clay that dropped. Step 4 - Waxing time - There are many many decisions to be made on this step. The different types of wax and sealants, paste wax, liquid wax will confuse even the most experienced car enthusiast. Do you enjoy waxing your vehicle every other week or once a month ? Then a very good quality Carnuba wax will work for you. Do you want the shine to last for 90 days or so ? The poly-sealant is right for you. Do you want to use a &#34;paste wax&#34; and enjoy a good workout for your biceps and triceps? Then a good paste wax is good for you. For me I want the shine to last for 90 days with minimal amount of effort to apply and remove. This is why I use Megiuars Tech 2.0 Wax which is technically not a wax at all, it is a synthetic polymer that shines very well. It will also last about 3 times longer than the carnuba wax and it is very easy to apply and remove. If you absolutely hate waxing your car and you do not mind the wonderful chemical smell, the once a year Nu Finish is actually a very good deal. It may not last a full year, but i tell you what, it is really close to it. I have used it and it works very well. It is also about $7 - $8 a can. Be sure to seal it up after you use it though, as it will age if you do not seal it up. But boy does it stink !!!  Have fun it is a great hobby !!
