I will add I’ve only tried VHT on the two I did and allowing it to sun bake didn’t provide good results and I had to start over a couple times. Heat gun made things much easier to achieve an even finish. I’m no purist, I think they turned out well but I’d be curious to see how much better something like the Eastwood would be. They seem to have good products.

Your last pic in post #8 looks great, hard to see details in some of the installed pics, same for the pic I posted earlier of a ~5000 mile 78 W72, but its a very heavy wrinkle texture.

Compared to the original one in my 28K mile 81 pace car that is very a light wrinkle, almost more like a very light grain sand texture, the black paint on the steering wheel spokes almost has more texture than the collar!

Heres a pic of a collar I did recently with Krylon wrinkle which is more in the middle for wrinkle and what I think looks better than too heavy or too light. Pics were resized so might not show full detail. Im debating on selling it or saving for a backup if/when one of my originals starts flaking.. i have 4 or 5 other collars from parts cars i will be redoing sometime too.

Would anybody have the GM part number/group number? I can't find it in my 70 parts book or my 77 parts book.
They must call it something else.

Little hard to see but I get the idea. Pics definitely lose some quality when posted.

I dont see the hub by itself. Only with the formula wheels.

These hold no electrical charge and can't be powder coated like normal and take more time, and a different process. If you have a 69 - 72 hub chances are it needs more work than you may see.

Not looking to infringe upon a revenue stream:. These collars can be powder coated and the texture is perfect.

I am just trying to help the Pontiac community that I hav been a part of since I was 17.

Powder coating is a paint that is applied as a dry powder and then cured, either in an oven or under UV light. Powder is usually electrostatically charged, while the painted part is grounded. This allows the powder to coat the part consistently with minimal waste. Compared to conventional paint, powder coating is generally much more resistant to scratching and chipping.

Here’s some pics of two originals a 71 car with 28,000 original miles , it’s alittle faded but you can see the texture . The other is off my 78 Trans Am , another low mileage car with less fading. Lastly is a recently powder coated on. Texture is perfect. I screwed around with VHT and others and they have too much wrinkle.

Directions are on the can, with uniform heat like sitting in the sun for an hour or 2 or a heat gun or oven if you have one to use for paint/powder coat curing you can get very good results.

However if another person is offering the service with good results then thats an easier option but it can be done DIY for about $10 in paint the paint to match your interior if not black.

I believe there are 2 versions of the hub. Early version part number 13955 hard to find, later version 6000500 very common not same part.

Part number for early version is 13955 up to 1973 I believe, hard to find.Second hub part number is 6000500 easy find. At moment I don't have time to buy paint practice try again ect. Ill.wait for formulabruce and have it done correctly the 1st time.If I was still a kid I'd try it or retired ect but that's just me.

Someone told me the Harley engine wrinkle looks most accurate.

What is the difference in the parts? Different shape or dimensions or just a revised part # or casting process/vendor with no real changes to shape/dimensions?

I know based on seeing a lot of these over the years plus my own cars that the wrinkle amounts varied quite a bit over the years... there is no 1 correct finish for all cars, if it looks good or resembles what your car had, its "correct."

Hey Bruce,
Still planning on another run?
Thanks

keep me posted

I will be ready to get more done soon. 1969, and 1970 collars have a longer turn around time as they typically need more work, which is hands on, intensive operation, and the main reason why the collars were textured in the first place. Due to the zinc in the ALUMINUM on the collar exterior, welding and thread repair is very limited. All collars need excellent threads for the formula wheel bolt on.
