For a simple modification, I just used squadron putty that I already had on hand to form this guy's ball cap. Despite not sanding it down enough, as you can see, I found it worked well and was shapable while uncured and quite "sandable" when dry. It looks much better from 10 ft away. I'm sure if I had taken more time I could have had better results. This guy was/is a Lemax Christmas figure I am using as approximately a 1:29th worker on a Roundhouse boxcar.
