Sigh... First DIY newbie mistake, get the tools too quick without looking.
I was about to paint my MPE tip today and realize the primer (rust-oleum) I got is not self etching and not for high heat, and without it the paint might fall off either during installation with soldering or later on when the exhaust heat up.
And I need to bring the parts to the dealer tomorrow so that I can get them installed by Friday pick up
