Re-doing the paint on the front bumper cover of the Jetta. Has a few knicks and scratches in the cover along with a crack or two I've repaired with two part.
Can I use the wonder primer to help fill in the tiny stuff on this flexible part? Do I need to add the flex-additive that is used in finish paint to the primer?
Plan is to just shoot it with some single stage and get it back on the road but it has a few pinholes and rough areas that I would like to be able to block down.
Thanks guys!
