Following the instructions provided I put multiple coats of Dingotone top coat on a guitar about 5.5 years ago and it still hasn't cured. Can someone please suggest something (drying agent ?) that might trigger curing or alternatively can you suggest something (e.g. Acetone ?) that will take off the top coat without destroying the underlying stain job. I am really over this and the lack of response I got to this same question 5 years ago.
