The matter of icing (and de-icing) wouldn't be a matter if the INDUSTRY would take it seriously.
At the times being, there ARE paints and coatings enough durable to make almost all ACs "NON-ICEABLE".
There are paints to AVOID graffiti's stick to walls, but OWNERS do not want to spend in those paintings.
There ARE coatings that AVOID 100% a possible surface icing of ANYTHING. Mainly sub-products of SILICONES.
IF those coatings/paints were used, it would be 100% recommendable the "russian de-icing method" shown in a previous post video
