Hi, After 5 years, the bolt and nut on the bracket that is holding the muffler are rusted off and causes muffler falling off. I find the similar bolt and nut with grade 8 from Sears hardware store, and have them installed. Now, the question is whether there is some kind of chem spray that I can use to spray and have bold/nut last longer? thx
