For small private aircraft why not be sensible?
If its going to cost an arm and a leg to do it properly, forget it. The cost far outweighs the runnings costs. Cancel the flight.
Or, rather than use some cowboy method, why not wait until it goes naturally in the sunshine, otherwise cancel.
Why mess up a lovely airframe with some micky mouse system for the sake of an hours flying!
Its knowing when not to go flying that is sometimes the better bet!
