Pretty sure that Legendary are two piece though they are vinyl upper and lower whereas the originals are vinyl uppers and leatherette paper lowers (steamed and stamped over backing blocks)

Chroma Premier runs about $110/pint -
4530S 58.2g
813J 40.8g
808J 30.9g
802J 26.0g
806J 88.8g
819J 7.4g
891J 3.9g
864J 2.5g
62320F 162.2g
62330F 112.1g
This makes slightly over a pint.

I mixed the following for shooting the wheels -

6 Oz above paint
2 oz Flattener ***
3 oz Chroma Basemaker reducer
2 oz Catalyst

***WITHOUT FLATTENER it will not have the correct sheen -ALSO if you don't use flattener the color will also be off SIGNIFICANTLY *** flattener actually lightens because is is really just talc.

I used a SATA knock off and shot it from 15-20" or so away - 20# at the gun with the trigger pulled -(across the pressure drop).
I sprayed a med 40% coat with the wheels starting the gun running from the center of the wheel through the low areas where the lugs are then up the skirt for all low areas then the spokes - then rotated on a hub and sprayed the lip the skirt and the center - making sure to get the wetness pretty even and about the same across the wheel -
after doing all the wheels - while still really tacky...
I closed the volume completely then opened until it just began to spray then 1/4 turn more open ---
 Then came back to the first wheel  - spun on hub---  and misted from 15 inches, you can even run the air valve in on the gun bottom to make the atomization larger...  kind of dry spraying - allowing an even mist of paint to fall on the wheel. 

It took 10 coats to get nice even complete coverage. started on the lug nut areas and the deep pockets first because I knew that would be the difficult part getting coverage without making them look odd.

It would have been difficult to have the coverage be too heavy... resist the temptation to open the volume!

I have rubbed them hard with a wash rag and I get nothing off the wheel on the rag nor does it feel any different... We shall see, however it is catalyzed and I have sprayed chroma premier catalyzed on wheels and grilles for years.

Originality / 1970-1974 Z28 wheels - color...
« on: February 03, 2019, 05:53:50 AM »
If anyone were interested I recently went through a lot of trouble to figure out the correct color in Chroma Premier for the Second Gen Z28 wheels - I have never been happy with the finish of wheels I have seen on any restored car. (the 70 -72 Corvette Grille is the same color with texture as well)

Here are the results... the lighter photo is WITH FLASH the other two are without.

That's the correct column...
Here is my brother's 73 Z28 4 spd.

FWIW - When questioning suspect stampings from the 70-74 time period -
There are quite few very good examples of 70-72 LT1 & 73-74 L82 vette engines which have never been apart never been out of the cars which to compare to suspect examples out of F bodies from the same time periods.
IMHO the Camaro hobby is ahead of the NCRS guys when it comes to recognition of pads broached and stamped at the factory. -

With the NCRS now accepting Camaros and Chevelles my hope is they are not going to accept pads as legit which have already rejected as forgeries at MCACN - Supercar Reunion - Camaro/Chevelle Nationals. I only say this because - In my short time in the NCRS I have seen quite a few pads being referred to as original which I would reject outright as rebroached and stamped... the stamping may be PERFECT - it's the absolute fresh broachings on a 80k mile car with a rebuilt engine which bring the questions. Convincing me that every instance of this occurring is legitimate and that the factory did them ALL would be a long hill... READ- A REAL LONG HILL TO CLIMB!!!

The lamps are the same as 1968-1972 Chevrolet and GMC pickup Bedlamps located on the curve in the center on the top of the back of the cab.

Pictured are a 70 LT1 vette engine and 71 LT1 vette engine -they along with the 70 Z28 engine were all cast - machined - and built at Flint thus the broach marks should look similar.

There is nothing wrong with the tag at all.
That is a nice combination, a friend had a nice one in the same combo about 20 years ago.

10 (BLACK) X33 is the most faked tag that is produced...
A restored or well preserved survivor -  BLACK 1969 RS Z28 with Houndstooth is a SIX FIGURE CAR -- IF you cannot afford to lose your money and you are not an EXPERT THEN FIND ONE.

They were canted toward the exhaust because that is typically where preignition occurs- thus if you fire the plug closer to the preignition points "HOT SPOTS" -  you are less likely to have colliding flame fronts(detonation) which will destroy the engine. 
 
DETONATION is the collision of two flame fronts inside of the cylinder.
I have a book which shows photos taken by GM through a quartz lens of the entire sequence. Twenty or so photos of what happens during a pre-ignition situation illustrated in crank degree BTDC and ATDC.

What a rare color combo...Silver Grille would do wonders for the car.
IMHO I think it would look better without the Vtop or with a white vtop & white stripes

Can't imagine going through all that and leaving press in studs.
The date is odd to?
I have had these to 25 years, trying to thin out the hoard,lol

I would have to agree on that...
The pair I had - were 292's - with screw in studs, guide-plates, doublesprings w/dampers - fully ported, and polished D-shaped Exhaust ports- gasket matched on the intakes through the throats and pockets with the chambers smoothed of sharp edges- bronze guides - Teflon seals -  2.05 intake valves, swirl polished with undercut stems, titanium retainers, & 10deg locks.

I think you will find that they are plugged and redrilled... I had a set which I got with some parts back in the early 90's.
 186's use the larger flat seat plug with the 13/16 hex.

I figured it was for a tach...
I love it... SILVER /BLUE   - BLACK / BLUE  -  are my favorite color combos...

I would have to go back to the 71 period paint... so unique and very clean looking.
The pinstripes on the front fenders around the z28 emblems... the lettered 301.56 CUI man that is just too cool...

ARE ANY OF THE ORIGINAL GRAPHICS UNDER THE CURRENT PAINT - wondering about the colors?

I will tell you that you can add material where EVER you want using 3m auto mix flexible repair - rough it up using a RASP clean with ACETONE and then apply where needed, it will not break off or crack if you prepare the surface properly.  I think I used 2 complete automix sets for the reproduction bumper below...

You can see the rasp marks in the bumper and the 1/2" of additional material I added to the "wings".
