For now I got decent results with normal eight hours lol drying. If anything will try post cure heating to accelerate full cure and that don't require anything additional to make

You can also make you're own wipe-on finish with poly-u. It dries much faster than poly-u out of the can. Try 1 part poly and 2 parts mineral spirits, stir well, use a cloth or foam brush to apply, watch for drips/runs.
