Hello all I just finished using both products,what I found so far is Klasse harder to get off but good on exterior plastic ,LG leaves white residue.Shine and depth about the same smoothness the same.So only think left I can think of is how long they will last. Also Klasse is a polymer based and Liquid glass is carbon based.So thats it for now keep you posted on how long each lasts and quality of shine smoothness etc:Oh l paid 25.00 for the Klasse and 17.00 for the Liquid Glass.:bounce
