Blasting advice for my Charger project

[mopar4don]

I'm not sure which is the best way for me to go and need some advice.

The car has been stripped to metal. Quarter panels have been cut out, trunk floor removed.




My plan is to replace the rear frame rails and floor pans with some that I removed from a 69 4 door Coronet.




Some of my questions are

1) Should I get it blasted with the floor pans in or remove them?
I want to remove them BUT am worried about loosing strength!
If I remove them I can inspect and blast the inner rockers, torsion bar crossmember.

I thought it would be best to get the car blasted then replace the rear frame rails with the floors attached but..

2) When I blast the rear frame rail clip from the donor car. Because all of the pans are attached, I obviously cant blast inside the rails. How should I do this?

Thanks

I would and I did remove the floor pans to inspect/sandblast the inners, crossmember and framerails. I only used a small sandblaster to clean these areas. I don't know if you were planning on getting it all sandblasted at once or if you even have a small sandblaster. I would then set up a support for the back half of the car to position it so that you can install the rear framerail section. I assume you are replacing the trunk so you can then sandblast the insides then. If you really want to sandblast the framerails under the rear floor pan then you should remove it to access that. It is alot of work but it'll be done right. I would sandblast the rest of the car after all this.

I found a blasting company that rents out there booth. So I would like to take the car there once if possible.
BUT should I be concerned if I remove the floor pan?

I wouldn't be concerned about the cars stability if you only remove the front two sections of the floor, the car will get much weaker when the rear floor pan is removed, however.

If I didn't get a PM, I may not have seen/answered this thread, so, since I was asked, what I would do is blast that good floor pan separately, blast the good parts of the old car, put the good parts of the car (meaning the car) and the pan/frame rails in self etch primer, remove the old stuff off the car (remember, you didn't blast them), and then install the new stuff. Self Etch you can weld through it, you'll see it 'sinks' into the metal. The inner rockers, yeah, you won't be blasting the insides, but, they are galvanized, just clean them out the best you can, spray some primer then paint on the insides and you'll be good to go.

Now, time. It looks like you may be doing this yourself, renting a booth, I wonder how much they're charging you to rent their stuff? If they charge say half what I charge, that would be $75.00 hour, if you're learning as you go, the time factor may add up quickly. Post some pics when done, or, during!
