Any pointers or warnings other than (don't let it touch your skin)?

 

it doesnt really matter if it touches your skin whenever i remove my ac freeon it always touches my hand. But if you are going to remove it by yourself make sure you take out all the air before you disconnect the hoses or it will explode in your face causing damage. Press the little fitting by the front of the truck with something hard the fits in there and make sure all the free on comes out. Your hand and object will be left slippery but just wash it off and put like a rag so it doesnt spray on to the rest of the truck.
