Using cyclododecane in form of the prefabricated spray that is
available on the market has the advantage that it can be applied
in a small amount, so it does not stay very long on the treated
surface. The disadvantage is that it can develop a lot of pressure
while spraying. Therefore it is not possible to treat a smaller area
(just a few centimeters of diameter) and fragile flakes of paint can
be blown away by the spray. So the application of melted
cyclododecane, which stays on the surface pretty long (several
months) would be the safer alternative.
