Thanks m0use for your reply. I tryed it and the texture of the cake showed through, so I reapplied it over and over. This is how it turned out. I wanted a thick smooth look. This was my first atemp at ganache. I think I need to practice - practice - practice
It will look better with a layer of smoothed buttercream under it.
I can't remember if it has to get stuck in the fridge or not 
; I would say if the cake is going to site outside and it is really really hot out, I would put it in the fridge so that it does not melt on you.
No, ganache doesn't have to be refridgerated, it keeps at room temperature below 75F for 2-3 days. The reason is because you scald the cream. It actually usually has a nicer finish if not refridgerated, it tends to lose a bit of its nice glossy sheen when refridgerated.
MOuse is right, if it is going to be somewhere warm, you will want to refridgerate it until serving time.
It looks like perhaps you tried to smooth the top with a spatula? The trick is to pour without smoothing. It is actually easier to get a smooth finish when you don't use buttercream under it.
Make certain you are not actually cooking your chocolate, but rather letting the hot cream melt it.
I cheat sometimes, if the top surface doesn't look smooth, I wait until it is set, reheat a bit of ganache and sort of drizzle or spoon a drizzled look to the top. It will make a pattern if you let it drip off the spoon onto a finished and cooled cake. Sometimes I just zigzag lines on top. Shh, don't tell, haha!
Your cake looks really nice though!

I waited a awhile and poured, it was so thin i could see the texture of the cake. So i repeated it over and over and you still seen the rough texture of the cake. Then finally it was to thick as seen in the picture. I thinkwith ganache it take practise. Thanks for all the help.
The cake surface has to be fairly perfect and you are right, it is practice! But even the best of bakeries don't always have a perfectly smooth topped cake, so I wouldn't worry. You can hide a lot with a strategically placed rose or such, haha!
