Removing undercoating?

wow that underside of the car looks amazing! The underside of that took some patience and persistence!

I used the propane torch and putty knife as well. Then I used a wire wheel to clean it up. For the wheels wells I am putting on POR-15 and then putting Gravitex on top of it. I used a wire wheel for the underside of the car then I am going to put Gravitex on the bottom as well.

I am still wondering if I should put the hemi orange over the gravitex or just leave it the black Gravitex that I purchased.
