M2001 - your laying that paint on WAY TOO THICK. Going from red to black, you should still be able to see the red thru the black coats until about the 3rd coat. From your pics you have full coverage after 1 coat, which tells me your painting very thick layers. You have to resist the urge to paint thick layers, thin layers are your friend. The thick layers are causing your excessive orange peel....
keep trying, less paint, continue with just the hood until you get the process down pat...
