    You have some epoxy primer in a spray can. It says it has a potlife of 4 days. Does that mean once I use it, I need to use it up in 4 days or it won’t work anymore?

    I’m looking for a primer I can use in fixing dings and scratches. In some cases I will be down to metal and some not. Apparently etch primer isn’t good for spraying on paint so I need something else. Would the epoxy primer I mention be good for this? I would in some cases need to top this with a filler/sandable primer before basecoating.
