Nice piece of kit Jim, and a very useful item to have in your cleaning/detailing arsenal. I don’t have the Big Boi Mini R, but I have the Meteo Vac Sidekick Blaster and I wouldn’t want to be without it
The Sidekick is quite small and light so highly portable. I’ve perfected the art of drying my whole car with it with the long pointed nozzle attachment - as you’ve said, the technique to drying the whole car is to ‘chase’ the water off each panel. With a well protected car, after the final open hose rinse there’s not much water left to chase off the car. I get rid of any remaining water droplets with a Wo-Wo drying towel.
The Sidekick Blaster is also very good at getting water out of all those annoying crevices that seem to retain water and then dribble down the vertical panels when you think you’ve finished drying. It’s a bit noisy though when it’s directed at water traps like wheel bolt holes and around the edge of the door mirror glass, although I find wearing a pair of ear plugs useful.
It amuses the neighbour when he sees me using it
