I cleaned up the underside of my 280Z just like you did. Except I found using the Eastwood pre-paint prep easily cleaned up the last bits of residue from the under coating. That was the only solvent I found that worked well. Awesome work and really enjoy your videos!!
I just stripped All the ziebart undercoat off my 72 Volvo, was a nightmare. Only thing I found that removes it is Goo Gone. Get yourself a few quarts, spray it on, let it sit 1/2 hour and all that will wipe away. Give it a final rinse with harbor freight degreaser.
In my opinioni youndid the right thing by removing all the old undercoating, i only had a grinder to remove it, i hated every second of that job hahaha
The cavity spray is a moisture cured urethane, very tough paint. I’m painting the entire underside of my car with Eastwood platinum. These have a 6 hour window to top coat, after that, they need to be sanded. I’m top coating mine with UPOL Gravitex stone guard, and then finally body color.
@ Interesting … I had thought it was an oil-based spray that would wreak havoc with the topcoat. However, he didn’t use Eastwood’s Internal Frame Coating Plus. He used the regular Eastwood Internal Frame Coating. It is a phenolic coating, not a urethane, but it too says it will harden.

Another great video and impressive work. You are moving right along. I am excited to see you get the underside complete
Appreciate that! The underside is getting there!

Yeah it's not fun for sure
You may regret doing the cavity spray before painting and undercoating the bottom. It will cause adhesion problems where it seeps out.
It's all getting cleaned up this weekend with all of the rattle can primer etc

IF you ever do another job to remove undercoating look into using dry ice.
I used dry ice on the interior sound deadening and it worked quite well there
I wonder if you could get the car sealed/coated by dipping it like you can chemically dip it to strip it and like new production cars get.
I wouldn't be surprised if that was a thing
