Looks very much like the TV ad stuff except lots cheaper, so brings the question if anybody has used it and how they like it for what they were doing?
Rv can almost always stand some sealing on the bottom, so looking for good stuff to paint on, as I find using the undercoater is better/ more cost effective for spray can use.
I have used the rustoleum leak seal on a floating digital pool temperature sensor that would take on water and stop working. So far working properly for the past 3 months. I bought it specifically for MH use but have not used it there yet.
