if u want to know the truth. theres alot of sealers that will work just the same. ive used several kinds with no problem even after many yrs. permatex ultra black, optimum grey, motoseal, red and copper likely would work. 3bond has quit a few that will do the job. yamabond. honda bond. toyota has several that work which are made by 3bond. i dont care for the thin ones like motoseal or honda bond but its just preference. as long as it has some chemical resistance it will work.
