A customer of mine in is doing a 67 912 resto from tub up. The early 912s had the same issues with rust we do and even has foam in them too (just like our 914s).

He used a company in Ohio to dip the car and dissolve the crud (he did scrape off the tar) ans ecoat the entire car. He did the doors 1st to see if he would like the results, and wow! Looks like new metal.

Looks like Stoddard will be doing a full write up on this car at some point, but I was so impressed with the results that though I would share.

Dipping cars is something we never recommend. I have heard too many stories of people painting their car and then 3-5 years later it starts to bubble.

The problem is the acid, or whatever they use to dissolve the paint and crud, gets in between the layers of sheet metal where they were spot welded. Then leaches out slowly and causes bubbling.

I also speak from experience. We had a bugeye sprite dipped and through out the restoration liquid was coming from the seems.

but that's just my 2 cents. Hopefully your buddy got a good company that rinsed it thoroughly.

I disagree...

I had mine dipped in 1993 and have had no issues...

American Metal Cleaning in Cincinnati did it.

This was not only dipped, but e-coated. We have used e-coating in architectural projects in Hawaii with high humidity and salt air exposure and they've done well over the last 10 years, so I can't think of a better application.
My understanding is the "dipping" process" is using a sacrificial anode, and drawing the oxidized metal away, then putting a water soluble sealer on it, before e-coating. So not your traditional an acid dip.

E-coating done in Ohio, (IMG:style_emoticons/default/idea.gif) that is very tempting.

Any chance of getting the name of the place?

We have an e-coat system at work for coating truck bodies before paint. The stuff is tough! One of these days I'd like to try and get my 914 in there to get done. I'm definitely going to get my replacement sheet metal coated before welding them on.

If you did a 914, you would first want to cut the outer longs off your car (and of course properly support the car before doing that). The heater tubes inside will get destroyed by the dipping process, not to mention the e-coating process.

Doing a traditional dip on a car requires two extra steps that they never tell you about:
  1. You need to take a torch (propane works fine) and heat all the seams until you boil all the moisture out of the joints. You'll know you're done when the joints stop sizzling -- don't need to get the metal any hotter than about 230-250 degrees, so no worries about warping the panels.
  2. You also need to strip all the lead off the body after dipping, since lead filler is porous and the chemicals will soak into the lead.


Otherwise, you'll have the exact problem you experienced -- chemical leaching out later and ruining the paint job.

I'll get the full information Monday. My contact is out til Monday. I dropped him a call and he was playing with this and sent me some pics.

I would love to see a 914 done up. the doors and lids were $500ish and the body was something like $3500ish. So not an inexpensive process, but as close to new as possible.

We won't have to dip when you start selling bodies in white Pete! (IMG:style_emoticons/default/biggrin.gif)

I have used American Metal Cleaning as well for 914 parts. Three years later, no rust or paint bubbling.

AMC dipped my hoods and doors, the rest was media blasted. Been using them for years on motorcycle parts. They also do powder coating.

There is a place down in Jackson MS, that also does stripping and resotoration. They have a Pyrolytic Cleaning Oven, phosphoric Cathode Dip tank, and they have a deal with the Nissan factory to allow cars to be e-coated in the Nissan E-coat vat.

If you are just cleaning everything off the body, the oven is the way to go. If you are going to be fixing rust and e-coating the whole process is the way to go. You could even put the chassis back in the oven after dipping to burn off any residue that might later cause a problem.

I once dipped a Formula V frame and years later it separated at the welds between the roll cage and the engine mounting frame. Acid got into the welds through some pin holes
