I have been using a Spar Varnish mix, based on recommendations from several Fine Woodworking authors, including G. Hack. L. Schleining and R. Johnson. These recipes vary from author to author, but essentially say that a little tweaking is fine. This makes sense to me as well, the Varnish adds the alkylds, the oil makes the spar varnish an even longer oil, and the dryers do their work.
Problem:, No matter what recipe I use, 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? They do not have any surface texture to them, they look “dry”.
Here’s what I did: I sanded the top prior to adding finish with 600 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 400 grit.
Coats consist of 1/3 McClosky’s Spar Varnish (Red Can), 1/3 Danish Oil, and 1/3 Turpentine, and sometimes Japan Dryer.
Also, any advice on streak removal would be helpful.
