AMT 1964 Pontiac Grand Prix "WIP"
Posted by Goofy62 on Thursday, April 30, 2020 9:24 PM

Hi guys.

 

I started this project a few weeks ago, but had neglected to start a WIP thread on this site.

Better late than never! Big Smile

 

This will be another full detail build utilizing parts from several other kits as well as plenty of modifications and scratch building.

So here we go!

 

The chassis and engine compartment detail will be taken from the AMT '62 Catalina kit.

The most difficult part of that substitution is correcting the fit between the chassis and interior transmission tunnels.

I chose to handle that issue as depicted.

There will be a number of interior modifications to better represent the '64 GP interior.

Door panels have been removed for modification, and the seats/console assembly has been separated.

The door panels have been stripped of their original faint detail and it is being replaced with more defined detail, including re-scribing what remains and replacing the rest with new.

Likewise, rear arm rests are being constructed to represent the non-existant kit detail.

Front seats are being modified by re-working the bulky "skirt" area of the seat and adding detail to the seat back.

Continuing with the interior, some additional details were added, such as seat tracks to position the seats better in the interior, courtesy lights were added to the door panels, and roof liner and interior top trim is also being fabricated.

Extensive scribing and rescribing is being done as well.

All of the existing trim and panel lines are being re-scribed for better definition, as well as new panel lines being added which were absent.

Under the hood, the expansive original core support was cut back to more accurate proportions, and the support from the Catalina kit will be utilized, as well as the firewall and most other parts.

And finally, bringing us to the present, I have spent the past couple of days working out an issue that I had been wanting to tackle.

The solution is a bit unorthodox, but it worked out even better than I had expected.

 

I have been contemplating a good way to be able to display the model with the hood in the closed position, as well in the open position if desired, but preferably without having to resort to a hood prop, building working hinges, or settling for unsightly slots cut into the firwall to allow hinges to fold back into. (I really hate those!)

This is what my fevered little brain came up with.

 

First, plates with pins were added to the hood.

 

 

Next, utilizing the hinges supplied in the '62 Catalina kit, plates with slots were added to the hinges themselves to allow them to be quickly and securely slipped onto the hood pins.

Finally, micro magnets were glued to the back of the hinge and imbedded into the firewall to allow the hood to be snapped into place quickly should I desire to display it with the hood open.

The draw back is that the hinges are then loose parts when the hood is closed.

I'll have to keep track of those! Wink

 

But, all said and done, it works very well.

Following this for sure. In 1964 my parents bought a new one and I learned to drive in it! I started the AMT annual kit but built a skateboard and stopped models pretty much. Thanks for posting.

I like what you've done with the seatbacks Steve. The seatbacks are an overlooked area by manufacturers on many kits. I'm guessing layout lines and a number 11 hobby knife would produce the look.

I cut a square section from the seat back and replaced it with a section cut from an AMT '66 Nova door panel.

The rest of the lines are scribed in.

I decided that the "pin" system might lack some strength, so I ditched it in favor of a more robust "channel" method.

A little easier to install the hinges to the hood as well.

Some more progress photos.

 

The transmission in this project will be an automatic, but with zero early 60s Pontiac automatics available in the modeling world, something had to be muddled together.

I started with a Johan 1962 Olds Cutlass transmission that was so graciously donated by a member of another forum, which is about the closest thing available that resembles a '64 Pontiac "Slim Jim" automatic.

First the 4 speed was removed from the engine and a collar was added between the bell housing and tranny to add some length.

 

Next a longer tail shaft housing was added as well as some other details to help bring out the Slim Jim look.

Finally, some putty, sanding and primer to finish.

It's not an exact match, but it will be close enough.

Then I moved on to some more interior modifications.

A little more scribing was done on the dash to add some definition, and some defroster vents were opened up.

 

 

Then I moved on to some steering wheel issues.

The original '64 steering wheel had some repair issues that I really didn't want to mess with, especially in light of the fact that I wanted the car to be equipped with the transparent steering wheel, so the wheel from the AMT '62 Catalina kit was investigated.

I started by replacing the steering column shaft and adding a collar to be chromed for attachment to the dash.

My original thought was to use the center cap and horn ring from the '62 kit, but that thought didn't last long. Wink

I decided to pull out my Evergreen stash and start scratching. Smile

 

First I made the spoke portion with wedges of styrene sheet bracketed with thin pieces of stretched sprue for trim.

 

Then the center cap was fabricated from various pieces of plastic tube and rod.

Should be a little closer to correct for '64.

A horn ring will be added during the assembly phase, likely made from wire.

Time for another update.

I have finally begun throwing around a little paint.

 

First I painted the seats and door panels Duplicolor "Dover White", then the dash and steering wheel got a coat of Scale Finishes "Sunfire Red".

Next I threw together a custom mixed enamel that was designed to match, but slightly contrast the dash and body color.

Apparently I mixed it a little too good! Smile

If you look closely, you can see a slight difference between the dash pad and the area around the dfroster vents and speaker grille, but it's more of a variation in sheen than color.

I guess in the future I will need to be a little sloppier with my custom mix if I want more contrast! Big Smile

 

Oh well, it'll do.

I like the contrast in colors with respect to the lower door panels which provides a "carpeted" look. Are the holes in the lower panels assembly points when reassembling the interior bucket?

The floor and lower section of the doors will eventually be carpeted with embossing powder.

I have some metallic embossing powder which is a perfect match.

I paint the carpeted areas for a good background for the powder.

 

 

 

Yes, I drilled the holes in the door panels and floor for pinning the interior together upon assembly.

Finished the first couple of coats of "Sunfire Red" with probably one more to go.

I really like this color!

It's very unique.

Today I foiled the scripts and applied the final color coat.

 

Clear coating will commence this weekend.

Are you allowing a curing period for the base coat before applying the clear coat?

And yes that is a unique color. Nice to see non traditional ones.

I will usually allow at least 24 hours of curing time before beginning the clear coats.

In this case, it will probably be about 48 hours before I will be able to begin.

Last night I applied the first clear coat.

Today, I foiled and detailed the G/P badges on the front quarters as well as the hood badge, followed by another coat of clear to seal it all up.

 

Over the next day and a half it will get another 2 or 3 coats of clear making it ready for polishing and foiling.

So why do clear coat over some foiled areas and not others Steve? I'm assuming you're using Dupli-Color clear which looks as if it were already polished.

It's beneficial to foil and paint small details like small badges and scripts before clear coating just because the clear coats may hide some of the sharper edges of those smaller items, making them more difficult to detail later.

I always use the "foil under paint" technique for scripts, but it will not necessarily give you the best results for larger badges and emblems.

Over time I have discovered that it's better to do those small and medium sized badges after the color coats.

Then any painting that's required for the emblem can be done directly on the foil.

The clear over the top will seal the paint in and assure that the small items, like emblems, will remain in place forever.

I do prefer not to clear coat over the "main" foil, such as window trim and body moldings.

It can slightly dull the chrome finish.

 

I am using Duplicolor clear, and while it might look like it will not require polishing, there is some slight orange peel and blemishes that will benefit from polishing.

I always polish anyway, regardless of how smooth the finish, just because it provides a more realistic look.

Unpolished paint can often have an unrealistic "hard candy" like appearance that will benefit from some polishing.
