Best aerosol underseal I’ve ever used
At last, an underseal that works as it should. Sprays on brilliantly with good coverage and remains flexible when it dries.

Excellent underseal.
This is good quality easy to use under seal, it goes a long way, 1 can did 2 rear well arch inners and chassis area. The spray patern is perfect so there isn't much over spray, so very little masking is needed, it dries to a good textured finish and drives quite quickly, ideal to keep in the garage if you have a classic car and do your own welding repairs.

Great value
Goes on easy, not sure of longevity as too early to say, for the price if it protects for a year it would be fantastic value.
