I've had no luck with restoring zinc, maybe my Eastwood kit isn't up to par. Most likely operator failure. Phosphating coming out great, marvel mystery oil really made a difference.
Anyway, not finding a decent repop for the tailpipe clamps. Pulling my originals out to compare, pretty big difference, not to mention diameter. Yup, one bigger then the other. And beefier. Not a huge deal, I'll take another swing at it, but anybody interested, pm me.
