 Posted: Fri Jun 14, 2024 11:41 am Post subject: Epoxy Primer over OG paint |
 |
|
I'm pulling together everything I need to prime/seal up the underside of my 55 Type 1. The OG paint on many of the underside panels is solid. Whatever isn't I have taken down to metal.
I have been informed that urethane based primers will interact poorly with the OG paints of that era.
What kind of experience have folks had with laying epoxy primer over solid, original paint and blending to bare metal?[/b] |

As long as it's scuffed and cleaned appropriately, you shouldn't have any problems. The cut sheet for your primer will tell you appropriate surfaces. The only issues I've seen with epoxy is applying it over acid prepped surfaces.

| I got the advice from the primer folks themselves...I guess the best approach is to do a test shot over some existing panels that have paint on them and see what happens... |

| The factory enamel is as hard as nails and chemically dead. Clean and properly scruffed, it’s a perfect surface for epoxy primer. I don’t remove it if I don’t have to. |

Thanks for the response orwell.
That's exactly what I've been thinking, given how solid the original paint is attached to the metal...it does not clean back down to bare metal easily.
So it seems that if I get it feathered out where necessary and scuffed up and then get everything clean as a whistle I should be able to get a good epoxy primer on everything.
The trunk of my car is really clean, original paint so I've got some studying and figuring out how to light scuff, clean and clear coat that area.
