Intro



This is my first full before/during/after detail write-up. Over the past couple of years, I have had the pleasure of reading through a countless number of detailed write-ups by many talented detailers. While I'm not a professional, I am an enthusiast who really enjoys detailing his own (and friends/family) cars. I'm planning to do more of these in the future, so this certainly won't be my last. Also, I'm not a photographer - just shooting with a Sony DSC-W300 here. No tripod, no cool lighting. And in this case, not much sun either.





The Car



The car is a 1978 Pontiac Trans Am Gold Special Edition. It is my father's, and he is the one and only owner of the car. It was purchased new in late-1977 from a local Pontiac dealer, and has since accumulated merely 11,000 miles. The car is now over 31 years old, and is 100% original and 100% stock - down to the spare tire, floor mats, factory grease on the hood latch, and sometimes-shoddy GM craftsmanship. It has never seen rain and never heard of snow. This rare car in such pristine original condition is almost certainly one of a kind.



There were quite a few different Trans Am's produced in and around 1978. From this Gold Special Edition, to the infamous Bandit Edition made famous in the Smokey and the Bandit movies, to the Redbird and Bluebird models, to the 1979 10th Anniversary and the 1980-1981 Turbo Trans Am.



This Trans-Am has the official Y88 Gold Special Edition package, WS6 suspension package, and the desirable Pontiac 400 4-barrel (6.6L V8) engine. Many 1978 T/A's had an Oldsmobile 403 engine - GM ran out of Pontiac 400 units and switched to the less-desirable 403 later in the model year. It has a 3-speed automatic transmission and the larger Fisher gold-tinted T-tops. Due to GM's fantastic record keeping, it is unknown how many of these Y88 cars were produced by GM, or exactly how many still exist in original matching form today. Here is how Road & Track magazine summarized the Trans-Am, from a 1977 road test:



Road & Track said:
With its beating wings embracing the remembrance of an air scoop, the monstrous flame-breathing black and gold bird on the hood announces your arrival onto the super slab. Seated deep in this street-fighter's cockpit, with luminescent dials giving you a read-out on the beast's pulse, you are indeed 'King of the Road'. The other cars out there are nothing more than transportation devices, a collection of anonymous and dreary shapes lurching homeward with their anonymous and dreary occupants tired after a day at the desk. But yours is not just a transportation device. It is not anonymous and dreary. From the shinny aluminum and gold spinning wheels to the enormous rear spoiler, with the vibrating ghost of an air scoop that actually makes it seem to come alive with each pulsation, and with the shrieking bird on the hood, it is an orgy of image and power. It is a Trans Am.



Before a few weeks ago, the car had been sitting in my father's garage for about four years. Lack of time prevented him from using the car, but we decided it would be good to get it running again before this winter so it would be ready for next summer. The car was dusty, but very clean. Simply rising the dust away revealed the fantastic finish, and it was only amplified by a good wash and wax.





Process



Since winter is fast approaching here in New England, my plan for today was just a simple cleanup. The car won't be driven until Summer at this point, so the real full detail will come then. For now, no polish - just a good cleaning. I did not touch the engine bay, nor the interior (aside from a quick wipe down with 303).



The car itself isn't easy to work on. There are decals everywhere - from the huge eagle on the hood, to smaller decals around the windows and on the roof. Extra care must be taken, especially when waxing. It is also deceptively large - there is a LOT of surface area! The honeycomb wheels have sharp edges (the cut on my hand proves that!) and are also a pain to clean.

Before



Tons of dust everywhere, and old wax residue in many of the crevasses. Four year old tire dressing turned the white walls brown.

In Progress



First up was a thorough rinse. Just removing all the dust made a huge difference:



mini-DSC02353.JPG




Wheels weren't bad, no need for P21S or something similar here. ONR and a grout sponge did the job.



mini-DSC02354.JPG




Wheel done, now to tackle those white walls:

Using Westley's Bleche-Wite, great OTC product for this. Simply spray it on, agitate quickly with a brush, and rinse off.

Bleche-Wite doing its thing:

And results:

Wash with CG Wash & Gloss. Two bucket method with grit guards:

Post-wash. No LSP applied here yet. Dried with a couple of waffle weaves from DI.

Time for LSP, Megs #16 for the T/A. M16 was the first wax available for automobiles, launched in 1951. It has since been discontinued. M16 is a hard wax and can be tricky to apply correctly - thin coats are absolutely key.

Wax residue from the past in many of the tight spots around the car:

With the LSP applied, I did a quick coat of PB Wheel Sealant on the wheels. These pictures aren't the best, it was dark outside.

mini-DSC02419.JPG




And by around 4:30 it was completely dark outside. After shots would have to wait until the following day, so I just aired up the tires and put the T/A back in the garage for the night. One after shot at night, thought this looked cool:

After



I was hoping for more sun, but didn't get it. Here are the overcast shots of the finished product. Hopefully I can get some sun shots in the Spring:

Engine bay wasn't touched this time. I did catch the junk on the rubber gasket around the scoop, some 303 cleaned it right up after these shots were taken:

Thanks for reading! Comments and critiques always welcome! :)



Time: About 5 Hours
 
You did a good job with the wax, but I'm wondering why didn't you clay bar the vehicle before waxing? Without clay barring a vehicle that old wouldn't you just be adding wax onto bonded contaminants??
 
Thanks for the trip down memory lane, and the treat of those many photographs. However, are you sure the tires are original? I question that for at least 3 reasons. First is my recollection is that GM was using the RWL version of the Goodyear Custom Polysteel Radial (I can't remember what they called the RWL version, and Goodyear even was named a defendant in a lawsuit involving a fatal T/A crash). Second, I see no TPC spec on the sidewall, which would appear on the factory tires, and third, those tires have the temperature/treadwear/traction ratings on the sidewall which IIRC didn't appear until a few years later.

If I were the OP, I don't think I would have clayed with all those old decals on there, either. Besides, with only 11K in 32 years, I doubt it's been outside long enough to collect any bonded contaminants :chuckle:

More of a time issue than anything this time around. We just wanted to pull it out and start it up before Winter gets here, and I wanted to clean it up. The loose dust sitting on the car wasn't bad at all, it hosed right off. There shouldn't be any embedded contaminants, it was stored in a garage, never driven in the rain, and has no miles on it.

Good catch, you would be correct. The original tires are dismounted, and being stored in the garage. Honestly forgot about those, I had no intention of being misleading. :)

Lol I would! I'd just work around them, and c'mon you cannot tell me that after 32 years they're absolutely no bonded contaminants on that paint :2thumbs:



11k isn't much but 32yrs would be more then enough reason for me to clay bay the vehicle, but hey to each his own right?

Thanks, I was just curious myself but like I said you did a great wax job :cool:

I didn't think you were trying to mislead, I just didn't remember GM using Goodrich tires back then...now that I think about it, at that time I don't think Goodrich was supplying any OEM tires. GM was mostly Goodyear, some Uniroyal and General.

Very nice. How much HP do those put down? And I was suprised to see the speedo only goes to 100 mph!



IIRC the 6.6 T/A was putting out 220HP. All the GM speedos were like that in that era, the 55 MPH NMSL had been made permanent just a couple of years before.
 
Sweet. One of my dream cars as a kid. T/A's are quickly becoming very collectable.



Make sure you throw some fuel stabilizer in the tank!
 
A beautiful bird indeed! Thanks for sharing!





My neighbor has on in the same color but it has a smaller 5.3 motor with 40,xxx miles.





You may want to consider a different LSP with all the decals on the car though....something like opti-seal/Zaino CS so you don't have to worry about the wax catching the edge of them. ;)

That's about right for power, and you're right on the speedo too. In the mid/late-80s through maybe early-90s, speedos only went up to 85 MPH - both of these laws have obviously been scrapped. The car unfortunately has a lot of emissions crap which really limits what the engine can do. If that was stripped, the car would put down significantly more power.

We did! :D



Debated pumping the tank too, but there's no easy way for us to do that. Fortunately, the old gas is just about gone and it will be filled with a fresh tank for the winter (and not left to sit for years again). ;)

Very good idea. Opti-Seal sounds like a good plan - I'll use that in the Spring. :)







Thanks again everyone for the comments and feedback! :dance
 
awesome car! Thanks for all the pics. They're a great resource for someone doing a resto. I have a buddy that just restored his black '78 4 speed SE with the same 8"x15" snowflake wheels you have. Can you please post a pic of one of the original tires or at least post the size? I've read a lot of conflicting info on the factory size and you can put the debate to rest.



Thanks,

Andy
