Orange peel effect

I am an old git trying to waterproof a new model boat using EL2 Epoxy Laminating Resin.  The planks are Mahogany and I have stained it with Ronseal mahogany dye, then grain filled it with grain filler.  I have carried out a test using spare wood and the resin looks good when applied but forms streaks and separates after a few minutes.  I have also tried it after applying 25g Woven Glass Ultra Light Plain Weave, this gives it an orange peal effect.  What am I doing wrong.  Help please
Roy.

The temperature is quite low at the bottom end of your scale which is not ideal.  From the picture it almost looks like you need to brush on in thinner layers and build up a thickness that way.

All a wood varnish would do is to seal the surface -  you could brush a very thin layer of resin over the wood surface to seal it as well.

I will try to elevate the temperature. 
The photo's show the thinnest layer I can apply with a brush.  Should I apply the first coat with a lint free cloth, or can I thin the epoxy, with acetone.
Once again, thanks for your advice.
