No tricks cab just small amount of lube, we actually use a dedicated hose assemble lube but any lite oil woudl work, even WD could work, you could warm the hose up with hot water bath or a heat gun but so far I have not needed to but we rarely use the stuff unless for customer.
In a pinch spit works better than nothing. I've done it that way more than once. Silicone spray works better
In theory, there is no difference between theory and practice. In practice, there is.
