We have purchased a 2018 Ford Escape and want to do the undercoating ourselves. There are many suppliers of the product for a do it yourselfer. Looking for the best product for the money. What is your experience with any of what is available?

I used some kind of spray can from Canadian tire store,,cost about 10$,,takes several to do truck frame and door cavities.

I think its same stuff most garages use,,last for a while..but I always get under the truck once a year and touch up whatever comes lose..
Also tried truck bed box coating on inside fenders this year,will see how long that last..

One time I bought old Monte carlo that first owner undercoated with some black hard shiny looking stuff,,not sure what it was though,looked hard and shiny like epoxy ..couldnt even scratch it,,

Most important is to wash and clean underside of the vehicle real good and make sure its dry,before painting it..not much fun but worth it if you like to keep it for long time,,my trucks is 9 years old and still
Solid..

Have steel wheels and those have started rusting because rain water sits inside the edge of it and doesnt flow out until you drive..
I used POR15 and bright aluminum over that,,
If there is any rust,,you should use Rust converter primer first..
