I ended up using med Ca and letting it hang in a bubble off the bottom to dry (surface tension is cool), filled in rather nicely, sanded fine and to me it looks like a GIANT flaw, a real road sign sticking up..this pen was for my wife so gave it to her to inspect, she couldn't find the flaw, barely even saw it when it was pointed out to her.
So I guess it worked just fine.
Thanks guys
