You may want to paint the dash with one of Sem interior paint products, This will ensure of a exact color match. So looking at this has left me with the prospect of trying to re-create one in Fiber glass without destroying a Mint original in the process. The reason for the V-shaped groove is that it provides something for both the plastic welding stick and padded dash filler to bite into and permanently adhere.

The only way to fix it then will be to go back through several layers of paint, texture coating and filler to get at the problem; this will require refinishing the entire dash again to blend the newly applied materials with the finished surface. Try to focus the sanding on just the areas that are thick with filler, otherwise you will end up with scratches in the dash surface that will take a bit of additional sanding to smooth out. If you find the filler difficult to sand, either use a new piece of sandpaper or apply a little more pressure.

Confirm this by using your hand to feel it there are any changes in the height of the filler compared to the surrounding dash surface. Before going to the next step, you must rectify this issue by cutting around the bubbling filler and removing it, sanding along the edges where the filler used to be, prepping with the filler prep solution and then reapplying the filler.

The FiberFlex will link into the foam and form a solid, yet flexible, foundation for the filler that will be applied.
