Lets not make this a flamed thread....now i agree comletely with bigboyhf, blackfire looks awesome when applied right away, best shine i have seen. Now the slickness definately diminishes and the shine is diminished slightly. Why? Anyones guess....so heres mine. Terry said BF is a combination of a bunch of specialized polymers, one for shine, one slickness, one strong bonding protection. Im guessing that while the protection polymers are very durable, the shine and slickness ones just seem to fade away rather quickly.
