Any one with opti problems, I might have a solution. About a year ago, i installed an opti on my 94 camaro. After hearing about the problems, and not wanting to swap to 95+ opti, I found a solution. I hit it with a scotch brite pad, and shot a clear coat over it.Havent had a problem yet(knock on wood). I think this is a good idea for nonvented type opti. Just trying to help some with the infamous opti problem
