Great
Better than I could have asked for. With proper prep, this underseal lays a very thick coat which dries well. Very easy to use when hooked up to an airline. Great peace of mind knowing my underside is coated with this

Good coverage and looks long lasting
This pack of three with a free application gun was well packaged and quickly delivered and once the containers were warmed up went on well with good coverage
