Why Clay-Bar 2-3 times a year?

After each wash, feel your paint. If it feels rough it means its time for a clay bar. What does a clay-bar do? It picks up the dirt and contaminants from the paints surface and underneath the clear-coat that do not come out from a regular wash. Clay bars help waxes and sealants bond to the paint for better protection and to prevent your paint from fading and losing resale-value.
