I am picking up a '73 tub on Saturday and want to get it stripped before I begin work on it. My body shop guy said he won't work on a car that has been soda blasted, and there are no places to dip close to here, so that only leaves me with some type of abrasive media, but one that hopefully won't warp panels in the right hands.

We used crushed and recycled glass. It takes longer than other media, but when applied properly it will not warp panels. It is surprisingly gentle on plastics, wiring, and other "fragile" parts as long as you don't dwell on them. It took nearly a full week to strip three layers of paint (the car had been resprayed twice in its life) and all of the undercoating.

I'm going to dip my next project - an '86 911 - to compare metal stripping techniques. I'll start that build thread soon.

We've had no issue with paint adhering to the metal post-glass media blast. You still need to prep the metal for primer and final paint just as you would any other project. We did not have to do anything special.

The ceramic undercoating went on without a hitch. The beauty of this product is that we can now spray the final color over it to effectively hide it (minus the texture, of course).

nice chris...can you share more about what the "ceramic" product was that you used...the +/- of using is...how it is applied...? also, is the tilt dolly a totally different dolly set up than the latest pics of the car right side up on its' dolly...??
I am wondering what is the best dolly set up to use to replace the entire bottom side of a 911 tub to have the tub be moveable, access to remove & install the new panels & be the best to support a tub w/o its entire floor in place while it is being replaced so not to wind up with a twisted & curvey potato chip when all done...

I plan on building quite a few 911s going forward, so I had several trolleys made. The latter trolley is for assembly and for moving it around the shop easily until it is on its own suspension. The earlier posted knock-over trolley is for paint and working on the underside of the tub. Both trolleys support the strongest part of the tub. The knock-over trolley bolts to the suspension mounts.

We're not done with the flares yet

I thought by ceramic coating, you were talking about a product similar to products used on heat exchangers, pistons, etc.

But now it looks the ceramic undercoating is really one of the undercoating sound barrier products that contains ceramic micro-beads embedded in a matrix of elastomer. Correct?

If so, i never thought of using it on the outside of a tub - I guess it is like using some of the Wurth flare protector type products (?)

BTW - IIRC, there is a major unit body sized dipping facility in the SE.

Thanks for posting about a very interesting build up.

Any updates?

[zyggy]

Almost 1 year anniversary anything new?

[chriskimmelshue]

Sorry or the long delay in replies and updates. What started out as a passion project has turned into a nearly full-time business. Therefore, updates are second in priority in the moment.

What seemed like an eternity in the metalwork phase then turned into another eternity in the bodywork phase. Finding a competent shop in my area was tough, but we stumbled upon an incredibly talented and skilled shop to help execute our vision.

Here is the body in rough metal as we dropped it off:



Note the reshaped flare profiles.

A polyester sealer went on and then it was time to use a little filler and rod to perfect the gaps:





Ready for the final sealer coat:





The rendering of the final product:

And, we're finally in the booth!











Wet sanding time!

Beautiful! The side-script is classy - how is it applied? Is it a custom thing?

Good eye. It is painted on and will be protected by clearcoat.

[Ferrino]

Awesome. Two more:

Which color? Is that the fabled "slate gray"?

And how did you generate that wonderful render?

[Crown]

Whow! what a beauty!

[cknaak]

looks great!

[wayner]

I was just in Nashville and missed this :-(

I love the stripe!

It is indeed shiefergrau. Glasurit's color information system still maintains the proper '63/64 year mix for the original 901/911 color and that's what we used. It appears the mix changed a little bit in later years.

PM me if you want a hand installing the head liner. I'll be in town again next month.

[stuartbrs]

Wow, love it.
