Others have reported good results using a spray lacquer, which with good preparation and polish afterwards should give a superior shine to CA and it will not be so susceptible to cracking and damage, but as said preparation is of paramount importance. And if the wood has any form of open grain a lot of coats would be needed to ensure a high gloss finish.
Melamine could be a good alternative but practice is needed to master it.
Personally I get good results with fresh friction polish with a finish of caranubia wax on top to protect the finish and maintain the shine, but as always good preparation is needed before the finish is applied, I sand to 600g always and sometimes even finer if the wood will take it.
I am thinking of trying the spay option soon, both lacquer and melamine versions.
