This method has been updated and now reflects the method I used in my actual build
I used black wood filler and dye on my build. I really liked the results so look forward to seeing the results of yours. I was not looking for a super smooth finish so I only did the grain fill once. If I had done a couple of fills it would be easier to get a flat surface. This seems to be what more experienced builder recommend if you are going for that look.
I have been using wipe on poly for the first time and can recommend as a great way to get a good cover. I don't have a great set up to spray when it is winter so I was looking for an alternative. I did do two very light coats of the Cabothane Poly Gloss before the wipe on as sealer as I had seen it as a recommendation to stop the dye bleeding into the wipe on. Not sure if this is necessary but it made sense to me and worked.
This was my second attempt with the dye... The first attempt, I went over it with dye too many times and the dye turned a green/gold/metallic colour. So, I sanded it back, went over it again with one light coat of dye, sanded it lightly... It's better now, definitely the colour I was looking for, although a little patchy. I'm not game to sand further as it's already close to the bare timber in places. But I think it will look fine under a gloss finish and black burst edges.
