Quarters

[elks]

New Quarters do you have to remove coating to prime.

[Lennard]

No, just scuff it with red scotch Brite.

New Quarters do you have to remove coating to prime.

The black E coat is just a "temporary" protective panel barrier coating for the mfg to store for some time period without having it flash rust, If you want to do it right, and do it once, remove the E coating and either "prime" with an etchant primer like Dupont's VARI-PRIME, or PPG's Epoxy primer, or primer sealer/etchant of your choice, but buy a quality product

[Lennard]

Yeah,  go ahead and remove the factory applied rust barrier.

This is what AMD says:

"Damage to a quarter panel usually requires the affected areas to be cut out (if it's severe) or hammered out and bonding compound to be applied and then molded to the desired shape. Auto Metal Direct quarter panels are made from heavy-duty automotive steel with an EDP coating for rust prevention and can provide an authentic original appearance and precision fit. Whether you're doing restoration work or rust repairs, Auto Metal direct quarter panels will make your ride like new again."

While I think EDP is fine stuff... I don't particularly trust that's it's done to a high standard on foreign replacement panels. There are lots of stories of it coming loose or not covering fully. It's even possible that the metal has slight oxidation under the coating. At the very least check it over thoroughly. A quick Google search says to wipe it with some lacquer thinner and see if any comes off.

I inspect every reproduction part that I buy - not just sheet metal - because I don't exactly trust that assembly line workers have the same interest in quality that I do.

Thanks Troy, I have 2 new panels I am about to primer and paint.   

[elks]

thanks for the info

[Charger-Bodie]

I leave the backsides of the panels in edp but the outside striped to bare and spayed with epoxy.



Like Troy said. Edp is great,but the prep is key. China isn't noted for there quality standards to say the least.
