Firewall paint and underside of car?

[Zach Carter]

What are you guys using for firewall paint and the floors on the bottom side of the car? Our 1969 Biscayne is at that stage of the restoration.

Thanks

i usually just use semi-black paint for gm firewalls and under body.
the name of the product i used was POR-15,it is also to protect the metal from rust as well.
my car never had a frame off but with some sanding and this paint it looks great underneath.

Most of the paint I see used is too dull it actually had some sheen to it, this is the factory shade on my 68 in the rear wheel house and frame and one with the bump stop removed to see the shade under it

What about the recently re-released GM Chassis paint #1050104? I think it has the correct sheen for this application too?

I recently used the SEM Rustshield black...very durable and it goes on nice. They offer a hardner/enhancer to give a little more sheen...it looks good. You can even put this stuff on with a brush and it dries so nice you can't see the brush marks...of course you need a good brush
