Warning: An old-timer in Cincinnati told me my weld-through primer was useless if I didn't scuff the factory e-coat first.
He said 'you're just painting over glass, kid,' so now I always hit it with a red scuff pad for 30 seconds before I spray a single drop, and my adhesion problems are gone.

It's amazing how often the real trick is just the simple prep work everyone skips. That old guy saved you a ton of future headaches.

Honestly robert_bennett29, how bad could those headaches really be?

That old timer sounds like he's been around long enough to know exactly which shortcuts bite you in the ass later. I bet he's got a crusty welding jacket with holes burned through it from 1987 and a coffee cup that's never been washed. Honestly, the fact that you only needed to scuff it for 30 seconds makes me wonder how many guys just skip that step and then blame the primer. I can picture some dude spraying over perfectly smooth e-coat thinking he's fine, then watching his weld-through primer bubble up like a science fair volcano. The real punchline is that the old guy probably learned that lesson the hard way himself, and now he gets to drop wisdom on clueless kids like us for free.
