I have 4 clear cedar 6x6 posts that we'll be scribing onto stones. I've stained / sealed everything with Penofin before assembly of the structure. But I'm wondering what a good product would be to seal that end grain?

I sometimes use Ipe Seal on other cut ends https://www.deckwise.com/ipe-seal-end-grain-sealant.html but it seems like either of those products could leach down onto the stone?

anyone found a good product to use in this situation??
