I was talking to a friend of mine today ,he owns a = Foreign Auto Repair shop,he doesn't work on vanagon's. But anyway he said he had = received a product memo from Auto Palace,which was informing him about a = new product that they are going to start to sell(he had forgotten what it = was called) that he though was called Blue Wonder or something of that sort. = That can be pored into the radiator and it is suppose to repair cracked = blocks and those sort of problems. Has anyone ever heard of this product,and will = it work on the Head gasket problem of the Vanagon's ? He also said the cost of = this was about $70.00 or so for it . So it doesn't sound like your typical = radiator stop leak product.Dose anyone have any comments or suggestions about this?
