I know, this is B Body forum, but, this is not my car. I have it in for Media Blasting on my rotisserie. Just wanted to share a few things with you all as I work this body. First off, the entire underside was coated with up to 1/4 inch of undercoating, and getting that stuff off is labor intensive. I heat it for a few seconds, then scrape it off. However, last night I found rust in the most unlikely place; at least I have not seen rust there in a car with this little amount of overall rust on it.
There is a hole about the size of a old dollar coin right in the crossmember, under the driver's side. This is a rust hole, amazing how it's there, and not in the floors!
I guess the lesson learned, and freely shared with you all is that wherever you are, get your cars Media Blasted, no matter how good of a judge you are in assessing your cars' conditions, the ultimate test is Media Blasting. Make sure to ascertain how much air pressure the blaster is using, what kind of media is he using, and, what does he use to knock down the rust? Ideally, it should be a soft media based material, low air pressure, anything around 30psi is great. Don't get fooled on air pressure; it's air volume that counts. Usually, a good Media Blaster will be relatively expensive because of the costs to run the equipment. I get $1800-2000 dollars per car, on the rotisserie, completely disassembled by the customer sans chrome trim, glass, handles, wires, everything...bare body, doors, fenders, hood and deck lid. But, the end result is an absolute sure knowledge of what's underneath your pride and joy. It can be a bitter sweet final result after visiting me.
Now, I'm not an advocate of Soda Blasting for stripping our cars. It does not eradicate rust, and, it is horrible if some is left behind, and you paint over it, and then it bubbles out, ruining your very expensive paint job. Soda Blasting is great for graffiti, pool cleanings, mold removal, etc.
So, this 70 Barracuda GS 383 has got some problems that the owner, and builder didn't know about.
Just trying to help anyone from skipping a very important step in their building of a car, or helping anyone in their builds.
