Rubberized undercoating is pretty popular. I bought 3 spray cans for two coats from the front to the back floorboards. And don'y worry about undercoating matching, you don't see it. I was going to make it the same color as stock, but when I realized it's not even the same as the body color, I just went with black undercoating.
Stock:
Overall looked pretty good, with the exception of one hole, tolerable, right?
Nope. After knocking all of the rust away, I was left with a large hole. I really don't have the tools, money, or real need to fix it professionally, so I did it the cheap way and filled it with foam.
After spraying. It works, very cheap and does the job. It may seem ghetto, but at least I'm the 1% that does something about it.
How it looks now
I still have to go over it again, I sprayed it kinda late so I didn't get it perfect. If I could get it all evenly, black looks good. I may be able to get it on a lift, wash it, remove what is loose, and spray it real good.
One of the members coated his like this:
