1 method I use is custom oil from brownells in spray can.spray light coat and strip with OOOO steel wool between coats until grain is filled in,then spray several light coats,being VERY careful not to have sags or runs,lightly roughing up surface between coats for better adhesion. You can get choice between gloss or satin and it looks a mile deep when done.
P.S. after sanding and before finishing process,hand rub stain in .
