My plan with the Milliput was to shape it in situ given I wasn't going to replace the entire part.  If only I could find the original I made..

Hi folks..
This is the canopy of Marui's 1/36 Aero Subaru.
What I need to do is make vacforming blanks for the windows because the original windows have poor fit and were crazed in the corners.
 

 
I have tried once before (and I can't for the life of me find the original I tried on!) by forcing Milliput through the openings until it was proud of the surface with the intention of sanding it back to match the contour of the canopy part, then separating it and vacforming over it.
 
I'm wondering how others might approach this.
 
I also have another kit which came with it's own 3D printed blank, but the layers were very pronounced.  What I did with that one was sand, polish and prime until I was happy with the finish.  However when I vacformed the canopy over it the primer came off in chunks.  Is there any way to get around this?

Cap, I'm doing this in TurboCAD Mac Pro v14. It's very basic, I have no idea how it compares to those others. 

Let me know if you want any photos....I've got 2 1:1 scale Tigers in my hangar

I do it from Craigieburn every day.  Just under an hour in good traffic..

Hey Kev...any time you want to come out and take reference photos let me know.  There's two in my hangar at Lilydale.

Looking great so far!
You use a similar technique to that I've used in making r/c model wings, in that you've cut and sanded all the wing ribs together.  First I've heard about shuffling them around to keep them even though!
I'm just wondering if you couldn't wrap the wings in tissue paper, then shrink the paper by soaking it in water.  That would give you the rib detail naturally.
You would have to build up a small area around each of the mounts for the struts and rigging such that they match the height of the ribs.  That way, you could punch holes in the tissue and not have to worry about it tearing.

Just a comment on the fit or otherwise of the nose....
On the real deal, no two are alike.  There are gaps of all shapes and sizes around the cowl, some fitting almost perfectly, others (mine, for example) with massive gaps!

You can get airfoil types from here.  The P-51 B/C/D used the exact same airfoil, ie the NAA/NACA 45-100, other Mustangs such as the V and VI used the NACA 66-(1.8)15.5 at the root and the NACA 66-(1.8)12 at the tip.  What those numbers mean is beyond me except that they're something to do with chord vs max thickness.

That is incredible.
