Of course, it’s one thing protecting your paint, but many forget it’s absolutely crucial to remove all those nasty contaminates first.
Still, that’s exactly where this well-priced professional clay bar can sort you right out. Designed to remove both organic and inorganic partials, leaving a glass-like surface they’ve rather cleverly formulated this one to be completely chemical resistant too.
This means you can save time by using a suitable iron remover (like their excellent Iron Max product) as a lubricant and remove all the metal contaminates while you’re at it. Bish, bash, bosh.
