LastPriest,
Nice philosophy. I also try to challenge myself in life's endeavors, and certainly when it comes to model building. I had no idea that you were so new to modeling as your work is outstanding for someone of your experience level. I have been building kits for about thirty-six years now, although my building slowed quite a bit during my time in the Navy. Fortunately, my wife is a good sport, and really did not get mad at all when I told her how many kits are in my stash when I sorted them out this past summer (just short of 900 at that time). Anyway, the more you build, the better you get, and the more you come to expect of yourself. It is a hobby, so please make sure that you keep it "fun" as it is called a "hobby" and not called "work" for a reason. Enough on that though as I am probably boring you now.
With my kit, which it sounds like is the exact same kit that you are building, I only used a small amount of Mr. Surfacer 500 on the fuselage seams. I spend a lot of time aligning parts and take my time gluing them with Tenax so that I minimize the need to fill spots later. This is rarely avoidable completely, but I seem to run into fewer problems than I typically hear of others having, even with the same kits. Even though I have experimented with some other liquid glues, I keep going back to Tenax.
A tip from my build; I did not glue the tails or wings into place, just inserted them. The fit is tight enough that they do not move, and the benefits are that I did not risk messing up my paint with glue, and if I have to move the kit, I have the option of removing those parts to fit the plane into a smaller area. Just something to think about.
