Wheel well sealer

[J_Speegle]

As mentioned the original spray guns applied a lot more product than you will see out of the modern guns today. This often results in more passes with the gun and in turn this makes producing details like shadows that look "real" (original) much more difficult sine each time you pass over to build up the color the gun and in turn the application is at a different angle and that softens the look of a shadow edge that originally was created by sometimes a single pass of the paint gun.

And for some areas such as the rear wheel wells we should likely IMO stop referring to the spray produced in the rear and front wheel wells as being overspray since this often leads people to assume that it was a mist and thin sort of an application. With the painters passing the spray gun directly over the open wheel well with the gun flowing 100% it in most cases created a nice coat of paint on the rear of the wheel well and exposed frame rail.

Back to the request and comments. Yes the green doesn't show up well in low light areas in you pictures so if the application is glossier and much heaver than it seems only you can see that given the color and the lighting. We see the same difficulty with other dark colors. Because of this I offer a couple of lighter and brighter original examples. As you and others view please understand these have often seen a fair amount so its not uncommon for the top paint coat to be warn away, in some cases down to the metal. Reason I placed the Don't symbol in the one picture since I know many will just look at the pictures and not rear the whole post


Hope these help. Need more or have more questions please ask. Remember that others will likely have the same or similar questions and that others will be viewing and reading these in the years to follow. One of the reasons we do this on a public forum

One's a repeat from early in this thread and a couple ar from one of the cars already shown but different angles and areas


In this picture we can clearly see all the white body color that reached the back of the wheel well area. Remember if this was cleaned up it would show even better how much paint is there




Back of the wheel well area (exterior or quarter panel to the left) showing the back and top of this one




Same car different angle and possibly other side of the car showing the top section of the wheel well




Picture showing how far back, of the wheel well on to the rear frame rail and other panels on the area, the exterior paint application reached on this example. From past experience I would bet that at least the frame rails on this car would be cleaned and polished to look as good as the exterior painted surface of the car just to show the amount of paint that reached that surface. 





And lastly. Though this is an example from another year I think the bright original color helps show the extent and amount of color one could typically find (plus the areas worn by usage and time) on cars like ours. Yes the exterior of the car had been repainted but they appear to have not painted over the rear wheel wells

So I have the floor and the wheel wells done getting ready to do the pinch weld blackout. Did the blackout go onto the lower cowl area under the fenders?

[Bob Gaines]

There should not be any paint on the floor plugs and sealer. Those were installed after all painting was done.Black out was done behind the rear wheel well and rocker pinch weld before fenders were put on. Don't overthink application. Overspray drifted onto floor pansand frame rails from application.

Thanks I left all the plugs and plates out did not hit the sealer. Thanks again. I know you say don't over think it, how far up should the blackout go up the rocker? Should it stop at the horizontal part of the rocker or doesn't it make a difference?

Pinch weld black out was applied from the very front edge in the front wheel well (no fender in place) to the rear valance. Typically the edge was pretty straight with a soft edge so often painters will use thin foam tape or back mask (bending the tape back over itself). At the front and rear of the rear wheel well there will be normally small sections where the spray entered that void when it shut off/ended the rocker panel section) and started up again at the rear of the opening.

Examples showing width and placement






Pinch weld behind the rear wheel well on the bottom edge of the quarter panel



Depending on the angle of the application nozzle about 90% of the paint didn't get on the pinch weld but sprayed on the paint shield or directly onto the section of the floor next to and inward of the pinch weld. Often leaving a shadow on the back side of the pinch weld. This will all be automatically done if you apply the black out paint in a nice fairly heavy single pass of the gun.  In the examples some of he black has worn away due to contact, age and exposure. Also when you look at some that are being restored often some of the black out paint was/is removed when they remove the Mach I style sound deadener from those sections of the floor






Hope this helps you and others

In the "69 Dearborn undercarriage restoration guide" last step talks about "backside of rear valance". Did that also include performing the same step on the shelby valance? If so is it only above the center opening for the exhaust outlet?

In general during years and models it was applied to the sealant (referred to as "cow paddies" by some) were typically applied at the end or ends of the valance not the center. Looked through all my pictures and could not find a good picture of the back side of an original 69 or 70 Shelby to determine if that practice was done on those cars. Maybe someone out there has a picture or pictures to further our understanding. Sorry

Here is a picture I got from Ed Meyer of the backside of a used Shelby valance showing the sound deadener just on the inside of the backup light hole.

Thanks Bob. Had 69 Dearborn Mustang examples so looks the same or similar.

I am guessing that there was not a need to change up what was done to the rear valance for a future Shelby so they didn't . For those reading AO Smith did tricky center opening cut.
