I'm thinking I might use epoxy primer followed by U-pol Raptor bedliner. I used this stuff on my truck and although it seemed a little too thin for a bedliner, I think it would make an excellent undercoating. Do a search for Lenie in the project updates section, he used it on the underside of his 68 Firebird.
Your welcome guys. It's a rare occasion that I get to help others out here. Like stated earlier, I think I will epoxy coat, rough up a little, then try this semi-smooth underbody coating. Who ever completes their's first, please post pics.

I use Raptor coating on most our builds and love the durability and texture. Make sure you have a clean well prepped surface though, I have seen it pull away from a concave curve from shrinkage. You can also tint to match, solids match the best, metallics are a off a varying amount depending on the color chosen. It is pretty close to a pebble grain if shot correctly

Several years ago I owned a restoration shop in Central Texas. I used Speedliner bedliner material as an undercoating for several muscle cars, trucks, and jeeps. I highly recommend the Speedliner product. The material had the best UV stability and color fastness of any of the bedliner materials at the time and believe that may still be true. I sprayed the material into engine bays in black for several muscle car/classic cars that the owners drove alot and wanted something that was easy to keep clean and still looked good. I did the complete underside, engine compartment and interior of my best friend's Chevelle SS @ 8-9 years ago and it still looks new. To my knowledge all of the other owners are still happy with their choices and still have had good luck with the Speedliner material too.
The texture of the material can be varied somewhat by the operator if they know what they are doing. It will still have a textured finish because of the spray equipment used to apply it, but you can change the texture from fine to extremely course. Personally I always sprayed it as fine as possible to give a semi smooth finish, that way very little dirt, etc gets stuck in the texture normally.
The Speedliner material has a slick urethane feel to it (it is 100% Urethane) so it gets extremely slippery when its wet, but this helps to keep it from getting dirty and worn out like some of the other bedliner materials out there.
Generally the Speedliner was applied to a painted or sealed surface that is scuffed up prior to application. Good prep and cleaning is the key to making the Speedliner or any bedliner material stick. The other big advantage to Speedliner was that it had/has very little shrinkage during curing.
Hope this helps anyone else that is looking at using this option as an undercoating.
would u want to use raptor liner on the sub frame as well, or just leave for underbody and trunk?
i would not use on sub. texture will make it look like you are covering something up. I have a 70 Mustang SCJ in the shop now and that is exactly what someone had done to camo old wreck damage.
