Best finish for mahogany entry door
We purchased an unfinished mahogany entry door for our front door. What is the best way to finish this door.
The door will not see direct sun - it is under the porch overhang on the north side of the house.
I've asked around and get lots of "don't use _____" from people, mostly citing that the finishes have a tendency to crack/peel and when they do the only remedy is to sand to bare wood and refinish. The door has much trim and several windows so the thought of sanding to refinish, even several years down the road is scary.
My sister uses Australian Timber Oil on a mahogany railing and seems pleased with the results and not overburdened by re-applying the oil periodically.
Does an oil finish like Aus. Timber Oil seal the wood sufficiently to prevent swelling and sticking of the door in humidity? Are there any other drawbacks?
Thanks for any advice you can give.
