NO. Only new cars should be undercoated. Unless you feel like ripping apart the car cleaning all the rust off then you could, but it is too much work.
The above answer is kind of stupid. The poster asked if a used car could or should be undercoated. If the car in question has rust peforation or is obviously rusted (and rust is easy to see and inspect for) then obviously the answer would be a solid "no". However, a used car that is CLEAN and well kept, has no rust issues, can be steam cleaned and undercoated. I have a 22 year old pickup truck that was purchased new in Hawaii, and soon thereafter called SE Arizona home until the past week or so. This truck has absolutely NO rust on it, and it can be cleaned and undercoated prior to it's first OH winter. SO the qualified answer is: If the vehicle is CLEAN, has been well maintained, or is from a rust-free environment, it can be undercoated.
Yes, it should be. The required undercoat/primer is available in Home Depot,less than $20 last time I used it.
If it's an old car you would have to clean all the crud off the underside and fix any rust and then undercoat it.
If you choose to undercoat, which is always good, go with something that is liquid and stays liquid. A rubberized undercoat gets hard and cracks, trapping water and grime on the frame causing rust and rot.
Yes. However, if you have surface rust, it should be removed before the undercoating is applied.
No, undercoating should last for years.
Yes, but it's not as good as using primer.
Painting will be a good option to prevent rusting.
yes you should have a undercoat what ever it means
Yes, Shih Tzu has an undercoat.

You can clean and reapply more undercoat.
