I use peruity seal or clear coat from tamiya
Is is enough to avoid chipping? Can you move the elbows, knees, etc. without needing more touch-up everything? I mean, the CanJoeCon exclusives are not chipping proof (i.e. Hailstorm). I'm not sure that just a clear coat is enough to avoid chipping when playing with a fig. I'm sceptical

I use it also and i have used it on jo stuff, my custom snow cat has not chipped yet.
