I'm making several pepper-mills out of white ash and have found some of the turning blanks have more open pores than others and I would like to fill them in so the finished pepper mills can be smooth with a nice finish.

I have searched the archives on this site as well as the internet regarding grain fillers and the recommendations seem widely varied. I've tried applying multiple coats of Zinsser Seal Coat followed by light sanding but it seems it will take many coats to completely fill in the pores which is too labor intensive and time consuming.

I think well rated wood grain filler is what I probably should use but I'm uncertain which one to purchase and try?

Can someone give me some suggestions on which grain fillers work best and are relatively user friendly?

Thank you

Dom
