Epoxy resin falling down

Hi,

I am a begginer in carbon fiber and I am currently facing a problem. I have a mould that is similar to a U shape so when I apply the fist coat of epoxy resin it falls from the almost vertical sides and creates a pool in the middle, is there any tip to make the epoxy resin more viscous so it will not fall down?

Also I would like to include an image in the front cover of the carbon fiber as seen on the picture below. I have tried using lacquer after the carbon fiber part is done and did not work. I tried placing the image as a first layer in the mould before any carbon fiber, but it did not work either since the first epoxy layer did not adhere to the image. Any ideas how can I make this? I was thinking on pasting the image once the carbon fiber part is made and then apply a thick coat of epoxy resin on top of it, but I fear it will drip down and would not leave a uniform layer.

Regarding GC50 as the Gelcoat, I would not recommend it, unless you have a way of spraying it on to create an even layer.  Otherwise, if you lay the image sticker on it, an apply pressure (the water bag) you may get noticeable distortion of the image. (And of the CF outside the image.)

I would go for the 2-component clear coat to finish the product.
