Question
I have been using a Spar Varnish mix, per recommendation from Fine Woodworking. Problem: I have streaks in the finish when viewed with raking light. The streaks are with the grain, so I am doing something wrong with application or wiping off, right?
Here’s what I did: I sanded the top prior to adding finish with 400 grit, and it looked great. Denubbed and got all the dust off. I have two coats on now and can see the streaks. Between coats, I have sanded the finish with 600 grit. No gum, all white swarf. Coats consist of 1/3 McClosky's Spar Varnish (Red Can), 1/3 Watco Danish Oil, and 1/3 Turpentine. Any advice on streak removal would be helpful.

Wiping or brushing applications always leave marks. You can minimize the mark by using the right technique of brushing and wiping, but it is rather difficult. Thin your material with longer dry solvent, and brush your material little by little. The best way to get remove the mark is to apply your material by spray.
Or hand rub out the oil as applied until the finish seems slightly tacky. You will feel your palm heating up as you rub out the finish. If your palm starts to stick to the surface add or prime your hand with a little thinner. Do a test on a scrap piece of wood so you can gain some more experience.
