1. Sanded a new profile for the HS caps so they are the same as the elevator caps, and also straightened the gaps between them. I was pleased to find that the extra work I'd done yesterday to eliminate air voids worked very well. There were only a few surface divots I'd have to address. I headed back home to get some two-part lightweight filler -- the stuff I've always used.
2. My panter saw me preparing to use "my" filler, and that's when something magical happened -- he introduced me to Dolphin Glaze finishing filler. I swear, if I had known about this product eight month ago, I might be flying my airplane right now. It is FAR superior to everything I've been using so far -- it's super self-leveling, sets up to rock-hard in about 10 minutes, is easy to wet-sand, and feathers like a dream. I feel like building another airplane just to use this stuff some more.
The bottom line is, my repair job on the HS caps turned into an easy day-and-a-half job, and the end results look fantastic. Thanks for the tip, Jim!
(There are still a couple of minor nicks, which he's going to address after a shot of primer tomorrow.)
