That doesn't look like undercoating, but it does come off easy.
The next video shows how to apply undercoating without cleaning the
underside of the car or masking off the exhaust.
I don't believe in any of these products, but maybe POR-15 would sort of
work if you took the time and effort to do all of the recommended prep and
applied all of the layers of all of their products, but it seems like a lot
more work than just doing it the hard way.
