I'm currently painting my '13 runabout, and noticed most of the door hinge screws are loose. A few weeks ago, there was a post on the subject which I didn't forget. A member mentioned he uses Kwik Poly. I decided to give it a try, and it seems to have worked well. I applied it to the pillars with a Q-Tip, which coats all the threads evenly, and there is still enough of the thread left to guide the screw back in straight.
Glad it worked out! I used the wood glue and toothpick method on Betsy, it also seems to be holding well.
