Most paint swirls are caused by improper detailing techniques. For example, when you wash your vehicle, dirt and sand get trapped in the sponge or mitt. The first time you re-wet your sponge in the bucket, some of the abrasive particles will come off the sponge into the water. Subsequent dips in the bucket will re-contaminate your sponge. These contaminants will then rub against your paint and produce swirls. To get those particles out of your sponge or mitt, you need the Grit Guard Insert. The raised radial surface fits in the bottom of any 5 gallon bucket and extracts grit from your wash mitt or sponge when you drag it across the Grit Guard. The dirt settles at the bottom of the bucket so your wash water stays clean. The Grit Guard has a radial grid surface that scrapes dirt out of your mitt or sponge. Four quadrants at the base of the Grit Guard calm the wash water and hold the grid above the bottom of the bucket. Dirt falls to the bottom and stays there. You'll be amazed at how much dirt accumulates in the bottom of your wash bucket!
Note: Grit Guard will NOT fit all 5 gallon buckets
