2-ND TIME said:Would a penatrating oil help at all? And or some hammering with a brass drift ? I have been using and, have found that Copper Cote lasts alot longer ( it also doesn't change the torque specs. One should derate torquing by 40 % when using Never Sieze. ) when used on under vehicle parts then Never Sieze. Girlfriend just loves when I am working with Copper Cote because she knows that she is going to get it on her.![]()
