Undercoating Options - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My truck was undercoated early in life. It is not the greatest looking option but it has done a good job of keeping rust away. Now I am in the process of patching an inner fender. I would like to re-coat with something after the repair. I am afraid Lizard Skin or similar would look much different than the current undercoating. Anyone aware of an option that looks similar to the current goop that I can apply at home.

I would try a can of spray bomb under coating. Wouldn't cost much.
Or check with a body shop that sprays Raptor. As I understand they can change the texture by playing with the air pressure.

My opinion is you will need an asphalt based undercoating to be a simalar match.

Here is one choice made in the USA..

There is this also.
I have used the spray can in the past.
