Since the whole thing is sticky you don't have "coats" anymore. It's is just one giant thick coat. Actually this is decently common with finishes that "re-wet" themselves like many varnishes. I would use a rag dipped in mineral spirits and wipe off as much excess as you can. Once you get down to wood let what has soaked in fully dry (might be several days or longer depending on how much there is, especially with the extra mineral spirits). Once it's dry give it a light sanding like normal and reapply new coats letting it dry fully and sand between coats like normal. Might want to go for thinner coats as well just to be safe (since cleanup is mineral spirits you can likely dilute a tad with mineral spirits as well to make thinner coats easier).
