Default Heat Shield/Cover Mock Up Materials

Hey I'm looking for some suggestions that'll make my cardboard heat shield/cover mock ups more accurate with minimal iterations. Maybe a bit noob but I've never had to make so many before.

I was wondering if you guys know of a good material/method that conforms easily to complex curves and can hold its shape/curve so I can easily transfer the shape to trim my mockup board.

Example: Trimming a shield to mate perfectly against the wheel arch apron around strut towers

I used some general wire but there's a bit of spring back so just wondering if you guys know of a cheap material that's good for this purpose.

Thanks!

lowes has thin aluminum sheets you can buy. depending on your size... cheaper if you get it online at a place like onlinemetals.

I've seen corrugated cardboard with sticks shoved in the holes. Close the hood and it contours to the shaped of it. Never worked well for me, but I've seen it work for others.

Haven't got to hood side yet but the stick idea seems pretty promising! Thanks for the heads up on that.

At work, we typically use Coltoflax (mainly used for dental moulds but also used for automotive). It's a 2 part putty with hardener and it's great because it's still rubbery when hardened and is easy to peel off (similar to plasticine). However, it's really high in cost so not a good option.

Would the thin aluminum sheets be that much different than using some alum foil? Maybe an ok option but I was thinking something closer to plasticine could also do the job.
