Choosing finish for mahogany project
I am building a new hatch for my companionway, and am using African mahogany. I've heard a lot of stories on varnish, and don't really know what my best options are. I chose mahogany for the durability (especially UV), and even though it looks great, I'm not after a $10,000 finish (this is for my 23' Coronado).
So I'm looking for experienced opinions on what I should consider using to finish this hatch. I would prefer the best durability with the least annual effort, and whatever I choose must be very good about waterproofing and UV protection. My guess is that I will be staining the mahogany slightly (has a dark pink color now), but I don't know if that affects the finish at all.
Oh, also; since the hatch will have many planks side-by-side, what is the recommended way to waterproof? Can the type of finish handle this, or is some sort of caulking required?
Any and all help would be appreciated!
