Defrost hoses.

[swamp rat]

I got some new defrost hoses a while back, there real sticky material and i'm having a bit of a time getting them slid over the heater box outlets and plastic vents.

I don't know what this material is but i am looking for a way to lube them up so they slip on instead of fighting them but not so badly that they will pop back off on there own.

After i got these i found out that there are 2 different typed of material used so maybe i should have gotten the other stuff??
