I am replacing the railing, newel posts and spindles in my house. What is the best way to finish them so they will be durable. I will be staining the oak, what is the easiest and best thing to put on top? I know conversion varnish is pretty awesome stuff, but I don't want to be spraying that on the inside of my house. I'm also assuming that the railings are generally fully installed with filled nail holes, then stained and finished? Any help would be appreciated.
Assuming you're staining the railing, I'd suggest polyurethane. Laquer lacks the durability to hold up for years , and poly is tougher. I prefer the oil based stuff if you can stand the smell. It can be brushed on or sprayed. Sand with 320 between coats.
If you're painting the spindles, enamel is the way to go.
