I'm looking at painting the underneath of my car in the near future so I have fully stripped the underneath and wheel arches of all old seam sealant and old stone chip plus completed any necessary welding.
I have zinc primed the bottom and I am planning on seam sealing the shell again and then re stone chipping the base with UPOL gravitex using a compressor and shultz gun.
My question is what is everyone's experience with gravitex? Is it any good so I won't need to do the process again and is it easily over paintable?
Thanks
Phil
