I have used the sanding sealer same coat process on all types of wooded doors we do,im not sure about long lasting protection this product just came out in the last i'd say 5 years.But as far as looks you cant tell any difference.
Yes these are brand names and im sorry if you live in the south won't be available for you.
But a good coat of sealer followed by 2 coats of satin 1 hour varnish will work great for you.I like the 1 hour oil based because it dries a little quicker so runs don't form as much.(because I like to use alot of product im not 1 to skimp om materials.
But if I can spray up then we use lacqueror,but you need not worry about that it dries so fast that it is not possible to brush this on,1 of my new guys tried brushing it and his brush was as hard as a rock in 5 minutes (had to be thrown away).
Good luck follow the directions on what you get and you'll be fine.
