Being that this is a undercoating product that it’s true quality is only proven over time, as far as its effectiveness I cannot comment on it at this time, however, my first initial thoughts are fantastic! The product applies very easily and coats extremely well, it looks great and you don’t have to panic if you get some on your exhaust system I had no experience of it burning. I have used fluid film in the past with less than marginal results, you have to recall every year, and it just washes off the underbody with weather and my trucks keep rusting! Those products work good in the doors but they are horrible for underbody it’s my true belief that this product will work fantastic, it really sticks to the frame and does not come off at this point I give it a five star review.
I had a concern because I had some over spray after treating my 2014 GMC Pick-up. I was instructed by PSC that it should come off with a little mineral spirits. I ended up using odorless mineral spirits from my local hardware store and it worked perfect.
