Loctite 492143, Aluminum,Stainless Steel, Multicolor High Temperature Threadlocker Industrial Sealant, 0.19 lbs

Much better than expected.This Loctite when applied to exhaust t bolts stops rusting !!!What? Yes!!!Also I found out when torquing ,the bolts can exceed the factory guidlines put a little more torque on the exhaust without breaking bolts ,.The cons are as expected,,takes heat to. break the bolts loose, so use wisely. Over all a must do, Exhaust bolts are exposed to heat and cold ,,in ohter words expanding and contracting making for exhaust noise, and retorquing the bolts at least yearly ..This Loctie solves that problem ,,,well worth the money spent!!
