Brik, this really isn't a big deal .Just be patient, it will dry . As most of us have done at some point , you just rushed it a little. I`ve told students before, " the time is gonna pass , whether you get in a hurry or not". In a worst case scenario you may have to rub it back[ after completely dry] and apply some more coats , which, if you do I`m sure , you will give it enough time to dry!! LOL!! To you this is a big deal but, trust me , keep building , and you will run up on another bump in the road that will make this seem like nothing . Keep Going!! Nate
