If you have the option, check out Glidden Endurance [it's along the
same price line as the B-M].
I have no recent experience with Olympic paint, specifically. Their
solid color stain is nice, but that's not what you want.
I used B-M a few years ago, so I don't know if they've done a
reformulation since. At any rate, there were no problems working with
it, and I haven't heard from the customer yet. I know those who swear
by B-M *really* swear by it.
I like Lowes' American Traditions interior, but i have no experience
with Lowes exterior.
