Thanks! I've never heard of using an additive with gloss black, or pinholes. I'll go search the catalog and threads and see if I can find anything.
I have been using Caswell Black Cat Urethane on outdoor things like car bike carriers, maybe I should try that on Yokes too. It's slightly satin-like.
Carwiz: Thanks, I do have some Alodine, I'll look into that.
Banditperformance: I've noticed that wiping with Acetone leaves a film on my parts. I'm not sure if I'm buying crappy acetone, or if it's from my rags, or what, but lately I'm having better luck just washing with simple green detergent and drying in the sun. It's certainly cheaper
After using it I don't see any residue.
