I have had finishes that never quite cured. Not hard if you live in a hot, humid place and can't let things cure at mfg specified temps. It can also happen if there is something over or under your finish that doesn't agree with it. All reasons to experiment.

However, there have been a lot of reports about Dingo Tone not curing properly, or having color changes when it cures. I would have used it on my first build, but for the fact that it could not be shipped to the US. I really liked the idea of "all natural" and "no harmful chemical ingredients." I eventually painted the guitar with Duplicolor, which also did not cure...but that's another story.

Meanwhile, I am not sure why PB still sells Dingotone (no one else seems to) or even what it actually is. Probably best to avoid it.
