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.
