We can tackle stuck nuts with anything and everything. Oil, heat, cold, violence. Motip offers the possibility of tackling such distress with a cold shock from a spray can. In practice, CO2 fire extinguishers were sometimes used for such a cold treatment. But that has caused several burned-out garages in the years since the extinguisher was empty if he had to do his actual work. The Motip 'cold shrink oil' freezer spray lowers the temperature to -30 degrees and also penetrates and lubricates. Motip products are among others available at Brezan, the car parts trade.
