While listed as a renovator, Autoglym also claims its product will clear stains, fine scratches and haze, using blended grains of aluminium oxide powder. The silicone-free paste could be used on fibreglass, stainless steel, chrome, alu­minium, brass and our door – where it worked very well. This Paint Reno­vator easily lifted any light scratches and, with only a little extra effort, eased out the slightly deeper ones. And the final sheen on this particular polish is the excellent price, which clinches it our Best Buy.
