how did you prepare the surface before starting? by that i mean did you sand it down to bare wood with a smooth finish? did you do any further preparation?
when we did it previously using the epiphanes we started with the smooth bare wood, added a sealer coat and then applied a few thin coats first with sanding in between. we were never able to get the grain completely filled in and after 4 coats we are sanding back to bare wood again.
