Flash times for most waxes are usually very temperature dependent. If the temperature is colder out, it will take longer for a wax to flash. If the weather is warmer out, it will flash much faster.
In regard to LVR 357 Magnum Wax in particular, Magnum Wax is extremely rich with solids. Therefore, in colder temperatures it may take even longer.
If we use 65 degrees to 85 degrees as our “control temperature range”, LVR 357 Magnum Wax should take 10 to 15 minutes to flash and then you can buff it off. If the ambiant temperature is colder than 65 degrees, Magnum Wax will take longer to flash and if the temperature is warmer than 85 degrees Magnum Wax will flash faster. Magnum Wax is not going to harden up like a carnauba wax and may remain slightly tacky as the wipedown process happens.
FYI: LVR 357 Magnum Wax takes a full 24 to 48 hours to fully cure. Don’t hit it with any detergents or cleaners before Magnum Wax has had time to cure completely.
