Whenever it needs it, just to the baggie test to determine this.

Baggie Test
Place your hand in a sandwich bag and rub it lightly across the clean surface of your car. The baggie will amplify any grit that is embedded in your paint allowing you to feel it. If it feels gritty clay it.

Alot depends on the environment and you really cannot say do it every .... I would check it every 6 months to a year. Most people will probably have to do it yearly if I had to guess what was average.

I use the Fine Grade on a fairly regular basis, after the 'bag' test as above, and if necesary a medium grade

Most manufacturers colorize the plastic to identify differing abrasive strengths (i.e. Clay Magic Blue is a fine abrasive, whereas the Red is a medium abrasive) It is also very effective on paint over-spray, if the over-spray is particularly heavy, you may want to seek the assistance of a professional. http://www.claymagic.net/

a) Fine- clay that abrades or shears light surface or imbedded paint contamination and encapsulates it.

b) Medium- clay is used to remove heavier surface contaminants (bird excrement and bug reside) it is slightly more abrasive than the fine grade and abrades the paint surface, while the clay encapsulates it

c) Medium to Heavy duty- clay is used to remove paint over-spray; it contains a slightly stronger abrasive that abrades the paint, while the clay encapsulates it

My car is garaged and not a daily driver. I haven't clayed it since December 04. I check it every time I add a coat of Zaino. It hasn't needed it.

My cars are garaged and I clay once a year.

If you clay that removes all of the Zaino off and you have to start all over again from scratch.
