Underhood Black

440sixpack · Feb 18, 2011

This is an originality question, but maybe it should be in the body shop.

When GM painted the black under the hood was it before or after the body color? if the black was painted first did they mask it off or just let the body color overspray hit?

depends on which black you are talking about. However this report explains everything clearly... http://www.camaros.org/assemblyprocess.shtml

Here is a quicker answer for you....

Quoted from above link -

"The last process for a non-stripe car was the blackout booth, where the firewall was blacked-out, the trunk was sprayed with spatter paint, and sound-deadening undercoat material was sprayed in the rear wheelhouses. The rear "cocktail shakers" on convertibles were suspended in the trunk for spatter painting, but weren't bolted in place until later in the Trim Shop, after the taillights and marker lights were installed."

This is all such great information. Thanks for posting.

So they must have masked the edges of the hood and shot the black last. I would have guessed they shot the body color last as then no masking would be required saving time.

No, I dunno the exact process, but I do know the underside of the hood is semi-gloss black, then body color was applied. There was no masking. Edges received full coverage with varying amounts of overspray on the underside.

Read the assembly process thoroughly just like James suggested. The firewall was blacked out last using a hand held shield. Coverage varies widely. If you can't find or substatiate data here or in the assembly process paper, just go to CRG and use the advanced search function. It's all in there with photos.

You seem to be asking about the black on the backs of the front end sheetmetal. These parts were "flo-coat/ flow coat" primed after being received from the stamping plants. (this primer is "black" it's not a pure black by anymeans, it has a gray sheen and is then painted on a buck which created a 2" or so gap around the edges.
Regarding the Overspray... The paint fell where it fell.
