Screen shoot of material used
This is the simple texture material that used to texture this images
Adding Water droplet
I have added water droplets added using geometry node. Here is the image of the node used
As you can see in the above photo I have duplicate the level of node multiple time. This will help to add more detail water doplet and make it look more realistic. I have provided a close picture to see how i played with different value to have add a realistic water droplets to the can.
Level 1
Level 2
Level 3
Final Result
At this point it's looking good with level 3, but feel free to play with different value if you want to get more droplets.
