Get the Erebuni shogun kit... it fits about 10000000 times better than those copies. I had the erebuni kit and it fit fine. Other have gotten the copies and they're thin and they didn't fit right.
Nah, your chop skillz are fine man. Just change the hue to match your cars color more. It takes a while, but it's worth it for that final product.
The cheaper kits aren't worth saving the money. They're flimzy. And they usually don't fit right. I wouldn't trust them. You have to pay the extra money for quality. That's always the case.
