If you are using a prewax cleaner, make sure it is compatible with sealants. Prewax cleaners meant for carnauba based lsps will affect the longevity of synthetic sealants.

Same here on the durability of FMJ. Last fall it was my go-to sealant and I still use it time to time. It's extremely easy on/off, and the slickness is top notch. To each their own though.
