Dynacorn sheet metal

[Barry]

I was just advised that the new Dynacorn (spelling) sheet metal is now going to come in weld through primer instead of e-coat.
If this is the case, you will need to sand majority of it off, you can scuff the hard to get areas but sand off what you can to metal and epoxy.
Zinc is great for corrosion but has fair to poor adhesion and small spots are fine but not a whole panel.

Guess I missed that one! Thanks.

Sad thing is they now charge more for the parts because of the weld through primer that we have to remove.

It's a lower quality primer that can be sprayed with conventional equipment instead of being applied with expensive immersion e-coat systems. It's a ridiculous move, and I would not be surprised if the parts themselves started to decline in quality as well.

Charge more get less that's the American way!

Has anybody expressed their concerns with Dynacorn? It's not common, but companies have fixed bad ideas in the past with enough customer complaints.

Think "New Coke"...

I will say that the quarter panel we received for 1966 conv that was sprayed silver with the weld through primer fit perfect. The one that is ecoated doesn't fit.

Dam, both my Dynacorn 65 'vert quarter panels are ecoated. Havent gotten to the point of fitting them yet. Fingers crossed.

This won't last long because the bodymen will ------*------- as history has shown before.
In past some of these company's would have the panels coated with lacquer instead of ecoat to save money and trust me they are saving a bunch spraying a zinc concoction on these panels vs e-coat. Enough bodymen complained and as far as I know they all converted but we still have old inventory that still needs to be tested when it hits the shop.

I shoot for AMD parts whenever possible and strip exterior panels anyways, where this would be a big hassle is on things like inner rockers or inner valance panels that we wouldn't normally strip, nor would customers want to pay to strip.. Rightfully so.

Hopefully they stick with the E-Coat..

 

[moparmusclecars]

So are the AMD metal panels ones that should be stripped before doing any epoxying and bodywork, or would they be ok just to sand up and go?

AMD has Ecoat from what I've seen but I still strip it all off in favor of SPI epoxy over steel. I've seen rust under Ecoat enough times that I don't chance it on most stuff.
