I did a test to attach a decal to a German Tiger tank that I can't even remember when (about 8 years ago?) it was made. A tank that was left in the corner. There's a lot of dust sitting there. I can't remember what kind of paint it was, but I think it was Mr.HOBBY or IPP paint. It was a tank I made for the first time, but I still remember that the color became very dull as I continued to practic..
