undercoating - sound attenuator

[desrocp]

I'm doing a full resto of a 69 Charger and had to replace all of the floor pans and had to work on the back quarters. Does anyone know how to replicate the ndercoating finish they use in the late 60s..I've tried a Shultz gun but not even close

I used SEM truck bed liner....Puts body shultz and rubberized undercoating to shame as far as durability and rigidness. As far as replicating the look, since it is spayed out of a gun, you could play with the preasure/needle setting to make it glob out a bit more aggressively for more of a factory look. Couldn't tell you if you could match the texture perfectly. I was going for more of a uniformed level coat vs. look.

some bedliner kits have something like paint rollers.. it gives you different textures.

Here check out the stuff Rick sells it's as close to factory as you'll get. You'll still use the Schultz gun, the trick is in the formula. http://www.restorick.com/products.asp?cat=11
