I'm going to take a guess here. Did you use lustercote? It looks like you used missle red monocote, and true red lustercote. Two different colors. I used missle red lustercote on my cowl, and it matches the missle red monocote perfectly!

Here is mine, I was happy with it. Not too happy about the "matching" paint I was suppose to have bought for the cowl.
