Hi everyone! I am currently encountering some problems when I used Tamiya Surface Primer Gray for a base color of Tamiya Pearl White (TS-45) for my Aoshima kit. I sprayed the TS-45 in a light mist coat on the body with the gray primer but the white color didn’t appear, only the gray color from the primer is visible. After waiting for 15 mins, I applied the 2nd coat (heavy) of the Pearl White spray can to see if the white color will appear this time, but it still remains the same. I also noticed that there were uneven painted areas and paint bubbles after spraying the body with the base color. Should I sand it down and redo the painting process? Any help and suggestions would be highly appreciated. Thank you very much!
