First time filling grain with Z-Poxy.
I've read thru many of the threads.
I have applied two coats and level sanded. No shiny spots, and the grain appears to be filled.
Some of the threads mention a final thin coat.
What is the reason for this?
Thanks a bunch,
Dan

Most of the time, provided all the pores are actually filled, it is just to even out the color on any sand through. If you didn't sand through and all the pores are truly filled you should be good to go.

I've never been a fan of thinning epoxy, and as Kent said, in your case it might be unnecessary.

If you are looking for a final thin coat I would just squeegee it well then warm with a hair dryer and brush immediately with a form brush. It will be thin, smooth and the heat will kick start the curing. (But just warm, hot will bubble it and that will be bad)

As others have said if you don't have sand through you don't need a final thin coat. I have found no problems thinning zpoxy as long as my shop is not cold and the zpoxy is not old and the alchol is pure.

For the last thin coat, I dab a little epoxy on the surface and then spread it around with an alcohol soaked swatch of rag. The rag quickly gets infused with the epoxy and it is a bit like French polishing. If the rag drags, you need more alcohol on the rag, this will be obvious. The object is to leave nothing more than a film with no real thickness so you the surface is very smooth, no lines from dust or the rag. I do this last coat even if I did not break through as it fill up any sanding scratches and really makes a nice surface for the next step. In my case, that is usually French polish. With these thin coats, it is helpful to let the mixed epoxy induce for a about ten minutes before spreading out. This helps the thin film cure well.
