I decided to take some quick shots of the non-slip coating on a late M1A1. This tank is still in its original factory applied paint scheme and has not been used operationally. You will notice that the surface differs. Some places the non-slip coating is really rough and in others, it is finer (but still rough). The final photograph in the album is an early M1A1 that is also in its original paint scheme. Its coating is not as pronounced and the application is not uniform. In fact in person, you can tell that it was applied with a brush prior to the tank being spray painted.
IMHO the coating on the Italeri M1A2 kit accurately depicts the non-slip coating used on late M1A1s and M1A2s.

Early M1A1 not so rough coating.
