Seymour Professional Rubberized Undercoating Black Aerosol 18 oz

Professional, paintable rubberized undercoating that forms a resilient, sound-dampening barrier on automotive underbodies, Seymour 20-46 seals out water, salt, chemicals, and road debris to help prevent corrosion and abrasion. It sprays evenly without sagging, dries to the touch in about 10 minutes, can be handled in roughly 6 hours, and won’t “bleed-through” when topcoated—ideal for cars, trucks, and heavy-use vehicles.
