Welding the exhaust...
On the cutout I want to spray this heat treated coating on it. Should I wait till after the cutout is welded into the y pipe and i pipe, or is it ok if it's painted? My dad told me if I sprayed it with this protectant it may not weld because it needs to be the bare metal.

Bare metal, and grind the coating off where you are going to weld. Non contaminated material to work with is best when welding.
