I use ganache to coat by cakes before covering. Some folk use buttercream, but I really struggled one hot summer (It happens!) with the buttercream melting under the cake and making it hard to smooth the cake or creating big air bubbles when left. Another cakemaker friend recommended using ganache, it is used by many professional cakemaker around the world, and I have never looked back.
Ganache is made by scalding cream and adding it to chocolate. It makes a beautifully smooth, liquid chocolate mixture that can be used in different quanities to create fillings or coatings. You can add flavourings to the cream to compliment your cake flavour if you wish, or leave it unadulterated.
In my experience, when administered well, ganache creates a firm, smooth surface which is the basis for a smooth polished surface on your cake. Of course, we've a bit to go yet til we get to that stage, but it's all in the preparation!
For milk or white chocolate ganache, I use 3 parts chocolate to 1 part cream.
