My new to me 03 civic sedan needs rust rehab, the rocker panels are gone and so is the rear bumper rebar, rear fenders and 2 spots in the trunk unibody.

My plan is to fix with new metal, but I want to use the same kind of undercoating as original, there is a kind of rubberized coating on the rocker panels and a different kind, a chalky black kind is used every where else under the chassis and in the wheel wells.

I think these are dealer or factory applied coatings, anyone know if they are available from dealer or 3rd party or what kind to order for it to match original. I have seen dominion asphalt type undercoating in a spray can in the store not sure if that’s the same. Anyone can you please advise,

thanks 🙏

Any of the rubberized undercoating will be fine. Then get it oil sprayed after all the metal work is done
