Walt, @luftwaffe-birdman
You have made a wise decision to shave off the "towel rack" antennae. I did the same thing with my ICM Heinkel 111 model. Unfortunately, when I installed the beam defense MG's, I managed to break off the barrels on both weapons. If I had another kit, and the opportunity to build it a second time, I would simply install the MG's and cut off the barrels, just as you did with the antennae.
One other "self induced" problem I ran into was when I was fitting the bomb bay into position. I didn't have mine perfectly centered, and this caused several builder induced gaps that likely wouldn't have been there otherwise. You can simply position the bomb bay racks and not glue them in solidly until later on when you are attaching the adjoining under wing panels. Your version might not even have the bomb bay as an option, and simply use the closed door blanking plate instead.
I'll bet this one is really starting to take up some room now ! Have you decided on which color scheme ? Winter versus standard splinter camo ?
I also used the Model Master / Testors enamels exclusively every since I started building models. When Rustoleum bought the company, and their "bean counters" advised them to discontinue this line of paint, I was shocked. Now, like you, I have been trying to find something that will work to replace my "go to" paint that I have used for nearly half a Century. I have been using "MRP" acrylic lacquer for some of my depleted Luftwaffe and US Navy paint stocks. So far so good...but it takes some getting used to.
I also ordered some of the Mr. Color paints, (along with a big bottle of the leveling thinner) primarily for my WW2 Japanese aircraft builds. Judging from your comments and seeing the spray card, they look promising.
Happy birthday to mom ...and take care buddy.
