The metal guy won't compromise

[Evans, Marv]

Fun! Keep us posted! I really like to see long noses being saved.

[Scooter]

This is NOT off topic!

I will be watching this thread for updates. Excited to see the results!

Mark doesn't like the tech forum and the people who sometimes populate it.

I think we can see that the car has not been dipped or media blasted. That looks like all hand work to me. I cold be wrong about some of the really hard to get at places.

What about that, Mr. Mark? Did they use any soda or dry ice?

[126coupe]

The metal man does not like dipping. The acids get under seams and the finish sometimes does not adhere perfectly, so we strip by hand (mega work) and media blast as little as possible. The rear and front were repairable, but he recommended new panels.
I plan on pretty close to perfection.

I've heard that media blasting can leave media, (sand/whatever), in crevices and cracks that keeps coming out forever. That it can be a real problem. It's too bad that you cannot dip the entire thing in zinc, like the factory started doing a short time later, to preserve the metal...or can you? I suppose none of these now valuable old cars will ever be driven near salt or stored improperly from here on because of their increasing value, so maybe it's unnecessary.

I prefer stripping by hand with a wire wheel anywhere there are seams. No media, no acid.

[Zeke]

Well, I've done a few myself and I don't dip parts unless it's a cast iron cylinder head. I don't have any experience with dry ice, but the concept sounds good. I will use sand or bead in selected areas and my favorite method is a homemade contraption modeled after one patented as the Vacu Blast.


(that's not mine)

I thought about buying a tub once from the premier fabricator Urs Gretner. His preferred method is hand stripped and touch blasted.

Sure, any blasting is messy. Have you seen how much crap flies around with the wire wheel? It's all a dirty business; strippers, blasters, wheels, etc.

BTW, if I understand Mark at all, this is why he doesn't post on the tech forum. Too many comments from the peanut gallery. He is kind enough to show us his interests but has no need for the extended conversation.

Sorry, Mr. Mark.

I sand blasted a 70 Challenger over 10 years ago. I STILL find a grain of sand in that dam car every now and then..

[Macroni]

Excellent!

[Shuie]

Awesome work.
