Used the permatex to adhere a dryer door gasket to the door. Worked as expected being a permatex product. Have used their products in the past with great success and so far this job is no exception. Will continue with their products.

Way cheaper than other places online and especially cheaper than the parts store. Exact product that it says it is.

Bought this here cause it’s significantly cheaper than auto stores. Exactly the same product, just much cheaper. Works great for repairing small engines with hard to find/make gaskets. Would highly recommend.

Works well, holds together well, dries reasonably quickly and has lasted over a year so far, outside, with no drying or breakage, sealing a smoker door (large temp variation).
