Hello,

While we were changing the hydraulic oil, old oil was spilled on the car body and belts.  
Can Dexron II cause decay of car body and belts? What should I do?

Thanks

ATF fluid should not cause a problem on the body panels. Just wash it off with car wash detergent, then a coat of car wax.  
As far as the belts, unlikely will cause significant harm. If not causing slippage you are probably okay.
