Once again an excellent write up Swanny.
I especially found your explanation for the 'cracking' of the Alclad finish a help.
I used the Alclad primer, black coat, then Aluminium on my P-38, 2 days drying time inbetween coats, and then 2 days after the final colour, she started cracking al over the place!
Back then I couldn't find anyone that could explain why this happened, and wrote it off to poor prep on my part.
Now I'm not so sure
(the P-38 has entered the ' when I could be bothered' section of the model closet)
Well done Swanny, and thanks.
