A question to all professionals in this topic:
You are landing on a Caribbean island (hot and dump) after a long flight at FL410 with your 604, for a short stop to refuel.
During the refueling/short walkaround you notice frost on the lower part of your wings formed by cold soaked fuel.
Can you disreagard it and takeoff?
Wait for an hour or two watching the frost to dissipate?
