Automotive Undercoating

[1G_DSM]

I've watched a few tutorials on YouTube but are their any tips or tricks to this? Most of the videos on YouTube have the car on a lift which I don't have access to.

The videos look pretty straight forward, but like I said I don't have access to a lift. Is there a certain shop that will not only do this for me, but do a superb job as well. I want to get my car undercoated ASAP after I buy some new tires (they're worn out and I rand over a nail while bringing the car home from my little road trip to go get it).
