Reply to "newbie with questions, be nice!!!!!!"

wow Marlin, Garth, Larry, thanks guys,
I run a restoration shop for a private collector here in Minnesota and we do a lot of mustangs , mostly boss 429s , boss 302's and boss 351's.
Our web site is kevinsklassics.com , check out our cars. this year we have 2 boss 429's going to Barrett Jackson this year and are lot # 1283, 1283.1.
So I'm really aware of the rust repair and labor that is involved. mustangs are really bad too, so i have seen the ugly side of this before, so I'm no virgin and i willing to step up and save this car!!!!! We have a paint booth and a car o liner spot welder, 4 hoists and 5 or 6 rotissories and have access to getting the shell coal slag blasted,no problem. WE also have tig and mig welder and I can cut off rusty metal with the best of them. My concern is that because of the structure design of the car and the abilty for the water to get into the sub frame and rails, i really want to do this one time and correctly. I have no interest in selling the car when complete. I have had the doors and hood ,hatch media blasted and there is ZERO rust. no pitting, pin holes, blisters, nothing,nice metal.
The rockers are severly rusted out ,as also the right inner wheel structure braces, I have one new old stock outer rocker , i will need the inner or middle section for both sides. The real concern is the rear engine area and the side rails in the rear wheel opening,
What if i drilled access holes to flush out the inner rails and then sprayed dp epoxy primer in the rails and then welded up the holes????? what about a por 15 sprayed into the rails, this stuff capsolizes the rust, i have use that product before and it realy works well. then replace the damaged areas,
Right now the car is on a rotissorie and completely disassembled.i want to do this correctly and this is why im here, for your guys input.
I have always dreamed of owning a Pantera and just ABSOlUTELY think it is a awesome car!!!
