hey, im guessing since its a civic the dash is just hard plastic wraped in somethin like my accord is, what your gunna want to do is rip everything off the dash down the the hard plastic frame and clean that up real nice with some soap and water then once its dry you want to stretch fleece over the parts you want covered then lay at least 2 layers of fibergla**, sand it all smooth and bondo over it all and sand some more til smooth, adding bondo and sanding it as much as needed til perfect. you can check out
