Default Undercoating

I know itís a dead horse, but what kind of paint should I use under my Jeep? I just spent too many hours revealing a very clean underbody, and Iím not sure if it would be a mistake to use this spray paint that I have:

I sprayed some areas last week, and find now it does scratch off pretty easily with sharp things.
The rattle can bedliner that I used a few years ago under my rear bumper still looks solid.
Iíd hate to get this far and use that paint only to have it not hold up at all.
Do you think that primer will be ok on top of factory primer or do I need a Self Etching primer?

Just finished prep on this. Scrubbed with purple power and wire brushes, rinsed, wire wheeled bad spots, 3M pad scuff sanded all surfaces, cleaned with simple green and rags. Going to give it one final water rinse and wipe down and let dry overnight then ready to prime tomorrow.
Need to get this done and move on though, time is short

What would you do?
Use the spray paint? Better spray like Chasis Saver? Bedliner roller or spray?

I used rustoleum "hammered" paint, on my bull bar. It holds up way better than bed liner to abrasion. Looks like powder coat.

Meh, I said screw It and went ahead with the rattle canning. Time will tell how it holds up!

I love how clean that underside came out.
Can only imagine the work it took to achieve that.
Once you have the Jeep back together I strongly
recommend throwing Fluid Film into part of your
maintenance schedule.

Yeah? On top of everything, painted underbody and raw metal of trans/t-case? If it helps be mud un-stock to it Iím all for it.

I live in CT where they use that crap on the roads in the winter.
I power wash underneath every October, let it dry and spray Fluid Film everywhere.
Even inside my uni-body.
I mean I go to town. 1/2 gallon at a whack.
Few things to know.
I will take a bit to burn off where you hit the engine, exhaust, ect.
It will not hurt anything and supposedly is environmentally friendly.
Your Jeep will smell for about a week. Some might say stink.
Every little piece of crap will stick to it.
When I wash my Jeep in the winter in the $5 automatic wash bay I do not wash the undercarriage.
Fluid Film will eventually wash off.
In April I power wash everything underneath as best I can and like what I see.
You will never truly get all the Fluid Film off when you do this.
I have been Fluid Filming for 5 years now and be willing to bet that there are nooks and crannies underneath the Jeep that have Fluid Film from the very first time I did it. LOL.
I only do it for the winter cause my goal is to hopefully never have to work on the Jeep in winter. If you do have to work under there when it is applied it is messy as hell.
