I always find that tamiya flat acrylics are quite delicate and do not like to be manipulated. They scratch and chip so easily. In addition, they looks too flat for me.
However, i think adding about 50% of the same color, but in the glossy range, will seriously improve the strenght of the paint. They still are not as tough as gunze acrylics, but it's better than just tamiya flat paint out of the jar.
Some also add some future in it, it is know to improve the toughness, too.
And this way, they also look less flat, with a more satin look, which i find better and more realistic.
Hope you will get back to this build and make it getting back in the straight and narrow !
Following the big Photobucket rip-off attempt, all my pictures on the forum cannot display anymore. I try to reupload the RFI pictures, but i'm not sure i'd have enough time and energy to reupload the pictures of the WIP threads. If you're interested in a specific subject and want me to reupload some pictures, just let me know.
