French Onion Soup

Hi, new poster, didn't see an "introduce yourself" thread so I'm jumping right in. I read through this thread and didn't see anything that explicitly said one way or the other, so, what's the ideal method for repairing/rebonding cracked transparent plastic? I've had an HMR VF-4 in fighter mode on the stand that came with it for a while, and the cradle that clips onto the fighter is stress-cracked in two spots on the socket where the stand plugs into it. I was thinking I'd paint the cracks with a modeling cement and seal them before they spread any further. I have Plastruct Bondene (the dichloromethane one) on hand, but it has almost never seemed to work out for me on toy plastics. Maybe this is a better job for the other Plastruct, or for Tamiya Ultra-thin? I know cyanoacrylate (superglue) fogs transparent plastic, so prefer not to do that if I can get away with it. Also, I didn't see it mentioned in here, but one thing I have had success with in the past is JBWeld Plastic in the syringe. I've found it's good for mechanically strong repairs to things that aren't visible or don't have to maintain a great deal of dimensional accuracy. IE, bosses that receive screws that have snapped off, or the backside of broken panels. There's probably other epoxies that work as well for the same thing but I can pick this stuff up at any hardware store. Unfortunately, I can't use it for this fix, it's pretty ugly when it dries.
