Hi Craig, I used the Passive 8 yesterday. Wow, very easy to spray and leaves a nice finish. Worked great on my Stainless Steel 32 year old Subaru silencer back box. I will definitely buy again.

Passive8.. is great!

Use it on every single restoration from now on here at Rusty Customs.
Works great as an internal primer for welding outer sills etc, then hit them with zero prep cavity wax for total coverage.
