What to spray on the inside of fenders and wheel wells?

So I'm finally getting close to painting my 68 Mustang. I stripped the entire car to bare metal all the way around. I then sprayed everything with Epoxy Primer. The engine bay I plan to BC/CC in a satin black. Should I do the same to the back side of the fenders, floor pans, and wheel wells or just leave them in black epoxy primer, or is it best to spray a rubberized undercoating on these areas. I plan to just use it as a summer weekend show car / cruiser. Whats the right way / industry standard for these areas and what products are best for these areas?

X2 for bed liner spray cans. Just make sure you can control the overspray as it is next to impossible to clean off

Myself, I stay away from the bedliner/undercoating stuff... If you ever want or need to do anything under the car the rubber stuff just makes a mess. Shoot it with your BC/CC satin black and call it good. Top coating the primer is a good thing to get it sealed up. Epoxy is tuff stuff but it should be sealed up.

They make some chassis black that is pretty tuff. Bed liner is fine in areas that dont get such high temps. I think some of the better undercoat and bed liners are heat and fire proof over 600 degrees and that should be fine for near the headers.

You can also look at the bed liner systems they often rent equipment and tooling needed to work with the product. They can also let you know if its going to stick and work in the under hood temps. I think rhino liner and the like are pretty tuff once they set up. Not sure of the rattle can stuff.

Hope this helps.
spray can undercoat --rubberized. I have 2 kars i put it on--- not show quality but i'm gonna drive this 55 It stays just fine. mo

get catalyzed, it's much more durable. The rattle can stuff is comparable to a rattle can primer. The two part stuff is amazingly durable. The Raptor stuff is good. SEM? It's been a while since I used it but it's great stuff. I sprayed the wheel wells of my mustang with it and it looked awesome.

I use the bed liner but just on the wheel wells where rocks and dirt can get thrown up, no where else.

I have tried most all of it and now do what is known to work..
