Odd that the Tamiya paint didn't cure properly. You could try contacting the Italian guy who's doing the YouTube build, he may have an inside track with Amati. Or maybe CMB, I don't think a direct approach to Amati gets very far. I'm not using the Amati pads, too heavy, just saying.
Be good to see how the hull rides on Thursday, don't forget some pics.
I'm not too far away from same outing, just need to get some new exhausts in and sealed, and maybe finish the underside painting now I've started it. A couple of weeks.
Best of luck.
David.
