Acid dipping in NorCal

I need a place where I can take a 914 tub (or tube frame race car) and have it acid dipped.

There has to be a place around Sacremento or Bakersfield.

Help Me.

acid dip

Are you sure you want to dip a 914? I've ben told by several body shops, rod shops, DO NOT DO IT!!!!!! They say you won't be able to het the acid completely out of the joints in the car and it will,1. continue to seep out after the car is painted, ruining the paint,2. continue to do the acid thing inside these joints and eat the metal away. Now, if you are dissecting the car for parts it won't matter. I've had the plastic bead blasting done and it is perfect! NO ptting, metal looks like it did when the car was built!

Hey Lew,

We have had several cars done in the past. We only do these to race cars prior to all the fab work. It makes for a very nice starting point.

Most places dont actually use acid. What they use now is nothing like what they used in the past (a lot more enviromentally friendly)

No, lews, you are on the right track. Any dipping is frowned upon by the concours weenies. It does get into the pinch seams and even after neutralizing, it can cause problems. For a race car, it's great. I think Brad once said that in the old days when they used real acid, the tub came out lighter in weight. I think Brad also said that a race car has a shortened and definite life span, whereas your car, properly restored, may live on forever. Well, maybe longer, anyway. There is a new show on Discovery Home and Living, "A Car is Reborn," about a Jag XKE 4.2. They did the media blast. Good show, it is from England and it is *spot on.*

In "Unfair Advantage" they talk about how some of the Penske/Donahue cars were acid-dipped specifically for lightening. Apparently some of them were so sketchy afterwards that the roofs were visibly warped and rippled, and you could see daylight through the sheet metal in some spots.

That degree of dipping is highly inadvisable for a road car, I would suspect

acid dipping

Soda blasting (baking soda, pressurized air and water) can be a good way to go, will strip the vehicle completly to bare metal, no distoration, nothing toxic. Except for the paint that comes off of the car. Easy on trim peices. Good process as long as whoever does it rinses the baking soda off VERY thourghly when done. Every nook and cranny. A rinse with vinegar when done leaves a nice netural metal finish to start bodywork and priming.

Yep.

We used to use walnut shells.

The problem is: none of what you mentioned takes off the seam sealer. This is where 914 rust likes to hide (under the seam sealer)

I want everything gone.
