https://flic.kr/p/2eKVkcY I’m at a bit of a loss. Every time I wet sand I end up with these darkish swirl marks that I can’t even see until I put another coat of tru oil on. It was building nicely and I wet sanded with 1000 and put thinned our coats on only to find these. So I wet sanded with 600 unroll they went away put another coat in and they are back. Any clue how to approach this? Thanks this place is a wealth of information.
