Welcome, Blake! One thing I would suggest is to NOT get in a rush to finish a project. Also, if you run into a frustration, step away from the workbench for a bit.
Decals can be finicky, especially depending on how old the kit, or decal sheet is. Some builders will shoot a coat of clear on the decal sheet prior to cutting them out and dunking them in water. When I do my decals, I start out with lukewarm water, and place a drop or two of dishwashing liquid in the water. I've had past experience with decals immediately sticking on a model, never to be moved, again! With the tiny bit of soap in the water, you will have more time to slide it into place, or straighten one like a custom side stripe before it sets. I always prefer waterslide decals to dry transfer, or the peel-and-stick variety.
And, to me, primer is a must!
Have fun, and post your progress!!
