I likes high gloss
Doing my '94 270 right now, I like a real high gloss. Sanding with 100 to remove old finish, then 150, 220 and 320 to remove scratches & get real smooth. Using oil based Polyurethane (all interior no UV to worry) that's personal preference. Sand lightly with 400 between coats. I like 3 or 4 coats, depends on how much grain you want to show, some places will soak it up more (dark places with visible open grain). I try to remove everything I can and refinish on a bench, also wipe down the piece with tack rag or cloth damp with mineral spirits before every coat. You don't want to start with dust on the piece. The wood is not "well matched" and the light stain is sprayed on so after you sand may need to even out the color.If you don't want to spend that much time I have done quick jobs using Formby's Furniture Refinisher or similar 'penetrating varnish' these are varnish with linseed oil added I believe. Use synthetic steel wool (000) or finer, rub on finish and buff with soft cloth, use a couple coats, real easy and looks good but don't last long, but real easy to reapply.There are as many methods as there are people, some like to start with thinned coats to act as a sealer. I'm sure you will get more replys including a few that think my method stinks.
