Over the next several weeks I will be practicing my technique. I am sure to improve. As I said, I was amazed at the detail that transferred. The cast has as much detail as the model. Also, the process was simple

Progress Update
 
I slosh cast another MKIV and was much happier with the results. The casting weighed about 34 grams before the windows were cut out. I used black dye in the casting material in order to get a good handle on what had been cast so I could use as little material as possible. The front wheel flares on my mold was not that accurate and so the cast will have to be reworked to fix that problem. I will post images of the second cast after rework and painting. 
 
In the interim I am researching the true colors of the four MK IVs that ran at LeMans and the one car that ran at Sebring. Below are what I consider the most accurate images of the cars and true colors.
 

Sebring 67

LeMans 67
 
Note some images of the Hulme car #4 are shown in a lighter blue. I believe the images below are more accurate

Rich that looks good.   Now get busy trimming out those windows.   I am anxious to see how it trims out.

Paints have been a real problem. Here is what worked. I used the duplicolor primer shown below  (middle can) and the duplicolor perfect touch red (not shown) on my test car. I followed this up with a coat of future. You can see the difference before and after the future.  I used the future only on the left side of the test car.  I have updated the original post for tips on painting.  This is not your typical model paint!

That came out nice.   I wonder if the true automotive paint is a base coat clear coat.     I paint over that primer and it never affects the top coat gloss.

Matt,

I really never even thought about it but you may be right. In any case the Future did the trick.

Rich, my Hobby Lobby had the resin and silicone all marked 19.99 today.    they said it wasn't a closeout but probably lowering the price to see how it would sell.

Rich - I always polish the Future with a paper towel after it's dry.  Paper towels have just enough "tooth" to smooth out small imperfections.


You can't always get what you want...

Since that body is a "science experiment", I would mask the future side and give the other side a couple coats of the duplicolor clear to see what happens!

Body #2 primed and painted. Body#3 primed. See below. The paint went on nicely but there were several "pin holes" (flaws in the cast). For body #3 I will use Tamiya putty to fix blemishes before paint.  I have modified the original post with images and more detail.

Update 11/15/20 - Two more casts (Body#4 and Body#5) - one success and one failure. I used too much casting material on body #4. The end result weighed 56 grams (much later I may use it as a prop in my track pit rather than making it a slot car body).  Body #5 was a success weighing only 25 grams before anything was cut out. There are some thin spots that I will reinforce so the end result may be heavier.  BTW, casting resin is very inexpensive. At $17.99 (after discount at Hobby Lobby), the kit will allow me to cast between 12 and 17 cars (This is an estimate - I have used less an one third of the kit so far to 5 casts)

 

Below is an image of the casts

Good work Rich.    The expense is the rubber for the molds.    I recycle old molds as filler in fresh poured rubber.   That saves a lot of material.

Thanks for the tip.  We will have rain for the next several days.  I should be able to work on the castings and make some good progress.

Even though you say the flares need more work - it still looks awesome Rich!

 

I presume I'll need to pick a number to order one from you when you get everything the way you want it!  LOL

 

Great work Rich - thanks for sharing.

Thanks Ernie,

These are coming along nicely. I don't think I would have ever attempted this if Covid had not struck - but with so much time on my hands I thought it would be fun to develop a new skill
