I used WMF for the first time last week. I too,was puzzled as to where it fits in my detailing regiment. My car already has a few layers of JW AJ on it,so last weeks detail was really just a "maintenance" kinda thing. After washing my car I QD'd with Sonus Acrylic Spritz and followed that up with a layer of JW AJT. My black 300C was looking stunning. I just couldn't stop there. (lol) Out came my new bottle of WMF. Using a dampened terry app,I massaged a small amount of WMF into my paint, working it in so there was little if any residue to buff away. ( 1 panel at a time ) Effortless application, really. Super easy to remove as well. WMF melts right into the paint. What struck me about WMF is how it seems to hide some minnor marring.( black paint shows everything ) Sounds strange to say this.............But WMF seems to "hide" not "fill". I finished up the entire car.........Stood back to admire my work...........Dripping wet & glossy. I'm a believer. My car was already looking great before the WMF,but it did seem to kick it up a notch in the wetness department. At this point,I wasn't sure if WMF was a true LSP. Rain in the forecast for the next day, which would've made for great testing conditions, but I just couldn't resist the urge to top it off with some AW. Here's why............IMO,the WMF initially has the look of BWW. But based on my experience with BWW which only provides optimum optics for 2 weeks,I chose not to take the chance. Now I know that WMF & BWW are 2 distinctly different products & formulations, I went with the "peace of mind" of the AW topper. I'll tinker with the WMF some more next week. So far........So good.
