I've used dye to add some colour to my latest project. It is just regular Rits dye, and I am happy with the result, but now I need to add some sort of clear coat to seal out moisture and add a bit of gloss. I have lots of tung oil and I was wondering if that makes for a nice finish over dye. Has anyone ever tried this or know of any reason not to try it? The dye colours are black and brown if that matters.
