BLADE and BRUSH

What time frame did you observe these cracks appearing over?
I usually let the wash sit for about an hour on the model before wiping away the excess with paper towels and cotton buds. On each occasion that fracturing occurred, it was apparent as I wiped the excess oil paint from the model. Unfortunately I can't say how quickly it appears because I leave the model unattended during that hour long gap.
Coincidentally, I tempted fate just today when I applied a turps wash on my Vehicle Model Tie Fighter. Despite my best efforts at not stressing the plastic, a couple of small parts broke off the model. Fortunately the damage was minor compared to my experience with the X-Wing and easily repaired. From now on though, turpentine won't be going anywhere near my Bandai builds. It's just not worth the risk.
