Surfaces protected with sealants are easier to keep clean as dirt finds it harder to stick to the slippery surface.
Extra Gloss Protection is not a polish, so will not remove or improve the appearance of scratchs, swirls or dull paint. If your paint has these problems use Super Resin Polish first followed by Extra Gloss Protection to lock in the shine.
Apply to clean, polished paintwork and protect your gloss for longer.
Pro Tip: If you use Extra Gloss Protection then you don't need to use a wax as well.
