Chemical Guys has been asked to create a premium formula to prep your paint so you can get the maximum durability from your sealant or wax and thus they created Vertua-bond 408. It helps clean the surface removing oxidation, surface contaminants, oils and more. This helps ensure a clean surface for more optical clarity in the clear coat. Many polishes have oils in them that help the polish spread easier, but these oils can remain on the surface after the removal process. The oils can also hide remaining imperfections and prevent your protection (sealant or wax) from bonding to the paint. By removing these oils you can expect to get more durability out of your sealant and wax. It also acts as a bonding agent to help you get the absolute most out of your next coat of protection. Sealants and waxes seem to react really well to this surface prepping formula and last noticeably longer. You can apply it by hand or with a buffer usually with a Black Finishing Pad. Vertua-bond 408 can be used after the washing, clay bar or polishing and before applying a sealant or wax. Use the Vertua-bond 408 to enhance the longevity and shine of your sealants and waxes!
