Im new to the detailing area and ive never done anything other than just wash my car with a little soap and water so i was wondering whether anyone could help me with this. what exactly does claying your car do and how does it effect the finish how do you apply it and take it off and what products are the best. also what is a good wax the only wax that i have ever used it eagle one spray on and it doesnt seem to last very long.

 

I tend to use the following analogy when explaining a clay bar.

A clay bar is similar to a loofa pad but for the paint. A loofa removes the dead skin on the surface of your body and brings up the new skin. The clay bar removes any embedded contamination in the finish and gives the finish a smooth feel. It also removes certain types of stains in the finish.

As for the wax, check into S100 (can be gotten at any Harley store), P21S, Meguiar's #16, Either of the Pinnacle waxes, or Einszett's Glanz Wax.

 

All of the above-mentioned waxes are great.

But there are so many different waxes/sealants which serve many different purposes. You have to specify what you're looking for in the wax before any good recommendations could be given.
Are you looking for durability? Gloss? Slickness?
