Yeah, i learned to not trust the manufacturer's claims.
Everything i read said that after a few coats of the matte sealer/finish, the pores would be sufficiently filled. LIES! Next time i'm using a proper pore filler first.
I agree that matte generally looks better with oil finishes. However, with every coat i put on, the figure in the wood looked amazing when wet, and the matte finish diffuses enough light when dry that it just killed the 3D quality of the figure. So i impulsively decided to throw on a coat of gloss and got the pop i was looking for with the figure, but it did highlight the open pores.
Ah, well... that's why it's a prototype! Maybe in the summer i'll sand it back, fill it and re-finish it properly.
