This is the first time I've built with this wood for a b/s set. Seems rather porous so I filled and sanded with z-poxy three times before beginning the sealant and then lacquer coats. I have a few other builds going simultaneously and they easily filled with a third the amount of z-poxy. Initial sprays still seem to show pores with the black limba. Anyone else run across this? I'm hoping not to have to sand back completely to wood, but will if I must (read into this, my hands and arms are getting tired). Only seems to be a problem in a few spots on the sides (and not limited to just black or white grained wood). Hoping for a simple solution, but know many of us (self included) tend to be OCD about these things. Any thoughts?

Not sure why this posted twice--perhaps Lance could delete one?

The name catgut is confusing. There are two explanations for the mix up.

Catgut is an abbreviation of the word cattle gut. Gut strings are made from sheep or goat intestines, in the past even from horse, mule or donkey intestines.

Otherwise it could be from the word kitgut or kitstring. Kit meant fiddle, not kitten.

Black Limba (Korina) is a fairly porous wood. I have finished it with no problems. Just sounds like you didn't get it quite filled in few spots. Options are to sand back those areas and apply a bit more of your z-poxy or to just fill with nitro. The additional z-poxy route may lead to coloration variations visible in the finish so I would just spray the extra lacquer at this point and give extra dry time before buffing.
