67 cuda FB progress UPDATE

well no pictures this time, but I am tire and sore.
I'm not sure how it's supposed to be done but I have been removing ALL of the under coating so I can epoxy primer the entire car. I have been using a propane torch and a scraper. I was successful in getting it all removed (almost).
How am I supposed to get ALL of the residue off, With Lacquer thinner, Grease and wax remover? There are a lot of nooks and crannies to get it out of. If not removed, I don't think the epoxy primer will stick very well. After epoxy primer, I am going to spray newer type of under coating on.
I sure wish I had a rotisserie to put this on, because working on my back with the cuda sitting only on jack stands is a real pain in the arse. I don't have much of any fingers left either. Any hints or tricks is appreciated.
Hopefully I'll have it cleaned up soon. I only have about an hour or two every other day to work on it. For some reason work keeps getting in the way.
Thanks everyone for your input.
