Replacement Panel Factory Primer?

[nestockcar]

I’m getting close to finishing installation of rear quarter panelson my 68 Camaro. The aftermarket panels of course come with some type of primer on them. Should this be removed prior to painting? It would be easier for me to media blast them now while I can take them off as I can save my garage from all the dust. Anyone with experience please let me know.

I don't know what these guys do with restorations, but I'm a body man and we've never stripped this coating off panels prior to painting at work.

oem parts I agree, aftermarket I dont trust it , I would da it and either epoxy prime or etch prime them

On aftermarket parts you will find that it is very thin. A 3M scuff pad will remove it very quickly. I too would remove it. Just to let the new primer get a tooth into the metal, That is what primer is made to do!

Asked Goodmark, the company I bought them from, here's what they said:

"The black EDP primer is bonded to the metal to keep it from rusting. You want to scuff, prime, and paint the part like you would any factory replacement part. Goodmark"

So, I'll give it a good scuff and prime. It seams to be pretty tough, so guess they used something of good quality.

Thanks all for your insights.

From what I've read, wipe it with laquer thinner on a rag. If it comes off on the rag, remove it all. If the thinner doesn't remove it, scuff and prime.
