8413 was designed as a non-sagging, firm, very flexible adhesive/seam sealer used to eliminate flutter of body panel cross members as well as reinforce them.  It is non-sagging so it can be applied to both horizontal and vertical surfaces and has excellent adhesion to almost any substrate.  It is thick set and can be sprayed with the proper equipment so you can achieve a variety of OEM finishes.  We offer our 300ml cartridges so you can complete more repairs and get a much greater value than you will with most other brands out there.  If you need a smaller kit, we’ve got you covered with our 200ml kit, product 8613.
