Hard to say when one hasn't been involved in putting the finish on directly. When I did my only attempt at TruOil finish, I put a lot of coats on, with the last 15-20 being thinned 50:50 with turps. That got pretty shiny, and as I'd been sanding it back from time to time, it was quite smooth. Never got to polish it back up as my final sand went through to the stain at one high point, so it all got stripped down. But it's certainly worth waiting a few weeks before final sanding and polishing as it does take a while to fully cure and go really hard.

Not quite sure what you mean about streaks, so posting some photos would most definitely help.
