I have about half a bottle of Blackfire Deep Gloss Spray ( BDGS) and am curious how much difference there is between it and the Blackfire Wet Diamond Polymer Spray ( BFWDPS) or have they just changed the name? I don't have any complaints with the BDGS but I am going to do my wife's car next week and if there is a noticeable difference I'll go ahead and order some of the BFWDPS and have it here to use by then otherwise I'll go ahead and use up what I have. Any comments or observations appreciated. BTY...I'll be working on a white Ford.
