Maybe it helps to create a stabilizd precomp for each surface (i.e for each individual, more or less flat, part of the car) that is overlapping with the removed object. Then you can do your painting / cloning work inside the the stabilized precomp. This means when you use the clonestamp, for example, you are sampling perspectively correct, i.e. if you copy parts from the far away end of the surface to an area more near to the camera, they change size correctly.

This tutorial gives you a quick idea of the workflow:
At the very end I do a quick clone stamp to remove the topmost window from the wall.
If you would do the same in the main perspective, the bricks you clonestamp would not fit that nicely in perspective: The bricks on the right side of the building are smaller than the bricks on the left side, if you paint in the original perspective. In the stabilized view, they all have the same size.

Also if your surfaces do not more (fixed rig + fixed camera) it might be worth to create the precomps. However, in this case you don’t need to track anything. You just create a corner pin manually and precompose to create the precomp yourself. You could also “fake” a quick track by creating a random mask with two identical keyframes, and then let MaskTracker+ create a precomp for you (Stabilized precomps are available in both MochaImport+ and MaskTracker+)

Cheers,
Mathias

Trying to figure out how to remove a rig planted on the back of a racecar running around a track, that holds 7 gopro cameras. There is no clean plate, and obviously the road, shadows and lighting on and around the rig change constantly. it's shot at 80 fps on 7 cameras so manual roto is virtually out of the question. And budget.

Ive tried a track matte over the rig (which is fixed) with blurred clone strokes but the background changes too much. 

Client does not want to hide the rig with a blur matte or cover up. Running out of options. Is there something I'm forgetting?
