Factory undercoating

[cawley]

Does anyone know where I can get undercoating that looks like the factory put on in the 60s & 70s. The same texture & look.:icon_smi:

Resto Rick's is one that alot of people use. Supposed to closely duplicate original(personally have not used it, so can't say)

Another option would be 3M #08864, used with a Schutz gun. (have used this and works well too).
You can get the 3M at any autobody supply.
