Make sure youre using either Z poxy finishing resin or west systems epoxy. Dont go using araldite or some other cheapo epoxy..youll end up with a disaster on your hands.
I use Zpoxy for grain filling on my guitars. I put on at least two coats of the stuff neat using an old credit card, mashing the resin into the grain and then finishing off with sweeps at 45 degrees to the grain. If after two coats Ive still got pores showing I dilute the finishing resin 50% with tech grade mthes ( I use it for frensh polishing) and wipe on a final coat using a lint free rag. Once set I give the surface a light sand with 400 grit paper.
I sometimes get checks in the tonewood I have in my shop. I usually deal with same by either working AR or PVA into the crack or if its really narrow Ill whick CA glue into the crack. Note that CA will stain light coloured woods...its not an issue for me as the cracks are outside the area of the wood I use.
